The combined entities texture for all layers except the switch layer was only built when the gametype has a front, speedup, tele or tune layer, which is only the case for servers declaring DDNet or DDRace type in their gameinfo. Now this entities layer is always built, as the game layer is always present.
Expose UI element ID for the main map editor as member variable so the select layer by tile funtionality can correctly be enabled when the map editor is the hot item.
Add/update doxygen comments for all `shell_*`, `os_*`, `secure_*`, `cmdline_*`, `windows_*` and related functions.
Move `open_link` and `open_file` declarations to shell group, to the same relative position as their function definitions.
Instead of sending the message from the first client which is not ingame, choose the first client which is fully empty, to make it less likely that the message is sent from a currently connecting client.
Add a country "none" with tee flag (code `-1`) and a type "None" for all servers without community.
Previously, the country and type for these servers was unset and their handling special-cased, so any non-empty country/type filter would exclude servers without country/type information. Now individual countries/types can be excluded without also excluding all servers without community.
Closes#7961.
It was possible to create a community/country/type filter excluding all entries when the list only contains one entry and right-click is used to deselect it.
Shutdown `CHttp`, i.e. abort all HTTP requests, as early as possible when quitting/restarting the client, after the config has been saved but before shutting down the gameclient. Previously, this was delayed until the engine shutdown, so the requests would often finish entirely instead of being aborted by the callback.
Previously, HTTP requests being aborted due to `CHttp` shutting down were considered `EHttpState::ERROR`, which sometimes causes deadlocks during engine shutdown or destruction of `CHttp`. The state is now set to `ABORTED` by passing `CURLE_ABORTED_BY_CALLBACK` to `OnCompletionInternal`. The otherwise unused handling of internal errors is removed.
Previously, it was assumed `ResultJson` would return `nullptr` for HTTP requests which have been aborted or failed with an error, which would trigger the newly added assertion error "Request not done".
Directly use the bounding box which has already been calculated for the text containers, instead of calculating the text width again for every info message text.
Reduce duplicate code by moving screen remapping and validation of the info message into the `AddInfoMsg` function.
Check for valid kill message before creating text containers, so they are not created and deleted unnecessarily.
Assign info message type directly instead of passing it as a separate parameter.
Combine `CreateNamesIfNotCreated` and `CreateFinishTextContainersIfNotCreated` functions to `CreateTextContainersIfNotCreated` function to reduce duplicate code on usage.
Extract duplicate code for determining name color in info messages as lambda function.
For consistency between 0.6 and 0.7 clients, also show kill messages for 0.7 clients, now that DDNet client also supports finish messages.
Closes#5623.
Instead of preventing the client from quitting/restarting while a warning is shown in the menus, add warnings that should be shown after quitting/restarting (i.e. the warning when the config could not be saved) to a separate list and show these warnings using an OS message box after the client has been closed. Otherwise, the client is prevented from closing if a warning is shown without being automatically hidden, which causes the client to hang indefinitely in the CI.
The message boxes for warnings must be shown after the client has already been completely shutdown, otherwise the regular shutdown with the Vulkan backend crashes because showing the message box has already partially deinitialized the backend.
The quitting/restarting client state is now checked after updating the FIFO component, so quitting/restarting initiated via FIFO is effective immediately, although this should have little effect in practice.
For completeness, a log message is added also for the case that the config was saved successfully.
The GitHub CI seems to automatically confirm/disable OS message boxes, so they should not block workflows.
Add assertions to ensure that the HTTP request result data and SHA256 are available when getting them instead of returning `nullptr` and `SHA256_ZEROED` when they are not.
Rename `CHttpRequest::Sha256` function to `ResultSha256`.
Because of incorrect index/size math, two favorite communities were removed when exceeding the maximum number of three favorite communities instead of only one. The check can be simplified because the maximum number of favorite communities can never be exceeded, so at most the first element needs to be removed from the vector.
Closes#7935.
Avoid many writes to disk each time the DDNet info is downloaded, i.e. each time the refresh button is pressed in the server browser, by first loading the DDNet info into memory and only writing it to disk when it differs from the current DDNet info based on the SHA256 hash.
The SHA256 is now also used to track whether the DDNet info was modified for the community filters and icons instead of using the current time for this purpose.
Closes#3941.
Initialize the HTTP client (start the HTTP thread) after initializing the network client instead of during the client interface construction. This ensures that config variables have been loaded already and the log output level is set correctly. This also means all library initialization log messages appear together in one block when starting the client.
Show an error message box and stop launching when the HTTP client could not be initialized, instead of launching but not being able to perform any HTTP requests, which causes bug reports about the serverlist being empty.
Both console and chat commands are sent to clients dynamically with respective messages, so the static lists of commands were only used for servers not making use of these messages. Instead of assuming potentially incorrect console and chat commands on those servers, the lists will now be empty for those servers.
Move the command registration from the `ddracecommands.h` and `ddracechat.h` header files to the `CGameContext::RegisterDDRaceCommands` and `CGameContext::RegisterChatCommands` functions and delete the header files. The `CHAT_COMMAND` and `CONSOLE_COMMAND` macros are removed, because they only add unnecessary indirection now. The strings `CHAT_COMMAND` and `CONSOLE_COMMAND` are simply replaced with `Console()->Register` and semicolons are added at the end of the lines.
Closes#7665.
Support adding up to three communities as favorites in the server browser. Favorites can be changed with favorite buttons which are shown in the community filter on the Internet and Favorites tabs. The commands `add_favorite_community` and `remove_favorite_community` are added to change the favorite communities via the console and for saving the favorite communities to the config file. For the favorite communities, additional tabs using the communities' icons are shown in the server browser next to the Internet, LAN and Favorites tabs. Each community tab shows only the servers from the respective community, hence the community filters UI is not shown on the community tabs but only on the Internet and Favorites tabs. The country and type filters on community tabs cover only the countries and types from the respective community. Favorite communities are added from left to right. When more than three favorite communities are added, the oldest (leftmost) favorite community will be removed from the list.
When starting the client for the first time, i.e. with `cl_show_welcome 1`, the DDNet tab will be created as the only favorite community and selected initially. The community, country and type filters are unset when starting for the first time, so the Internet tab now shows all servers per default.
When starting with a `ui_page` for a favorite community that is not configured, the page is reset to the Internet tab. This also affects those who upgrade from versions with the old DDNet and KoG tabs. The server browser is now also correctly updated when changing `ui_page` via the console.
Track country and type filters for every community separately, to avoid filters resetting when switching between community tabs or changing the community filter. The commands `add_excluded_community`, `remove_excluded_community`, `add_excluded_country`, `remove_excluded_country`, `add_excluded_type` and `remove_excluded_type` are added to change the exclusion filters via the console and for saving the exclusion filters to the config file.
Render community filters above the toolbox (filter, info and friends) tabs when on the Internet and Favorites tab, so this setting is more visible and can be changed also when the other toolbox tabs are selected.
Add icon for the none community, based on the tee country flag color. This icon is hard-coded in the client, as the none community also is, so fetching the icon from the server would be inconvenient. Load community icons already when rendering the menu instead of only when rendering the server browser, so the icons are immediately available when using the start menu.
Find tutorial server by searching for community type "Tutorial" instead of searching for "(Tutorial)" in the server name.
Avoid cleaning favorite communities and filters when there are no communities, i.e. when the DDNet info failed to be loaded or does not contain any communities, to avoid losing all favorite communities and filters in this case.
Closes#7774.
When empty PNG files are loaded, the `std::vector` for the file contents is resized to size 0, which results in undefined behavior when it is accessed with `front`.
When `io_tell` fails, i.e. returns `-1`, this was incorrectly cast to an `unsigned` and therefore caused a very large allocation and potentially crashes due to lack of memory.
Add `CGameClient::RefreshSkins` function to refresh skins. This function reloads all skins by calling `CSkins::Refresh` and then notifies all gameclient components about the skins being refreshed by calling the new `CComponent::OnRefreshSkins` function, so the components can properly invalidate their current skin texture handles. The existing `RefindSkins` functions are changed to `OnRefreshSkins`.
Additionally, `OnRefreshSkins` is overridden in `CMenus` to set the flag so the skin list will be updated before it is rendered the next time, to fix the client crashing when changing skin related config variables via the console. Closes#7891.
Reduce height and empty space and make margins consistent. Slightly increase width for better round corner drawing and to support longer vote descriptions.
Auto-scale description and reason labels and show ellipsis if they don't fit.
Show circular progress indicator for remaining vote time.
The functionality to draw text on the voting bars is never used, so the parameter `Text` is always `false`.
Remove unused variable `PassArea`. The remaining area of the voting bars is unused.
Use error log level for error messages. Use info log level explicitly instead of using `dbg_msg`.
Log time taken for initialization in trace level message.
Use `IGraphics::CORNER_NONE` instead of `0`.
Use `nullptr` instead of `NULL`.
Remove arguments identical to defaults.
Use loops for tab bars with several tabs.
Add parameter to `shell_execute` to either start the process in the foreground or background on Windows. Previously, all processes were started in the background, because this is desired when starting the server from the client. However, this causes the graphics initialization to fail when restarting the client after updating or with the `restart` command when using Vulkan with windowed and windowed fullscreen mode.
Closes#6578.
Render an additional "Reset filter" button below the "No servers match your filter criteria" message to make it more obvious for new players how to restore the original view of servers, especially when the filter tab is not currently selected.
The `bool AllowResizing` parameter is only passed to other `SetWindowParams` functions but never used in the end, as whether or not resizing is allowed is separately determined based on the value of the `int FullscreenMode` parameter.
Instead of cleaning the countries/types filters based on all available communities' countries/types, only consider the countries/types of currently selected communities. Ensure countries/types are always cleaned when updating the server browser filter in the UI. This fixes that countries/types which are not available for the selected communities were still affecting the server filtering, causing no servers to be shown in some cases.
Closes#7847.
To simplify the usage of the demo recorder, parameters are added to the `IDemoRecorder::Stop` function to control whether the demo file is removed or renamed when stopping the recording.
Ensure demo files of the replay recorder are always removed (except on crashes). The temporary replay demos were previously not removed when being disconnected from a server.
Fix auto demos being stopped and restarted when enabling replays in the settings menu. Now only the replay recorder is stopped/started when necessary.
Fix replay recorder being restarted when setting `cl_replay` variable with console without changing the value.
Remove unnecessary `CClient::m_ButtonRender` variable. Demo rendering is already stopped correctly when reaching the end of the demo without this additional variable.
Remove unused `CDemoRecorder::m_pMapData` variable.
Instead of leaking the m_MoveRestrictions to all classes which needs to
adjust the Character velocity, add a setter which takes into account those
restrictions.
The shotgun bug replication requires an access to the Velocity without the
restrictions applied (so we have to have this dirty setter).
Expose only *const* CCharacterCore to force the setters usage and prevent
incorrect write.
Ensure that the `CHttpRequest::OnCompletion` function has finished before updating the state which is visible to other threads. Otherwise, threads may try to access the result of a completed HTTP request, before the result has been initialized/updated in the `OnCompletion` function.
Fixes warning due to invalid texture width/height being shown for downloaded skins, because the texture was loaded before the image data was initialized. Closes#7818.
Regression from #7683. Before this, the `OnCompletion` function could also modify the HTTP request's state, which was used to check if loading the skin PNG failed. Instead of doing this, a separate check is added for the skin download task to check that the PNG was loaded successfully.
Use [virtual terminal processing](https://learn.microsoft.com/en-us/windows/console/console-virtual-terminal-sequences) for Windows console output when possible, using the existing async logger. Fallback to the old Windows logger when virtual terminal processing is not available. Do not set any logger when there is no console/file/pipe to output to.
This adds support for 24 bit RGB colors using ANSI escape codes (when Terminal emulator supports it) instead of only supporting 16 fixed colors.
Use the existing async logger also on Windows by converting the console standard output handle to an IOHANDLE. Avoid converting console output to UTF-16 by changing the console output codepage to UTF-8 and outputting that directly. Overall, this reduces the time until the loading screen first appears when launching the client from the console on Windows by around 70%, from 80-100ms down to 25ms.
Add support for `NO_COLOR` environment variable also on Windows.
Use the async logger also for writing output to files and pipes instead of using a Windows specific implementation for this, to reduce lags when redirecting the standard output.
Closes#3925. The client/server will not freeze anymore when entering selection mode in the console because we are using the async logger on Windows now.
Closes#1108. We were already using AIO on Windows to write the logfile, which was not causing any known issues. We are now also using AIO with the async loggers for console/files/pipes on Windows.
On Windows, the result of the `localtime` function is thread-local, hence our uses of this function are already thread-safe.
On non-Windows, the `localtime` function is potentially not thread-safe, so the reentrant `localtime_r` function is used instead with a thread-local buffer for the result.
Closes#7788.
When handling door and laser entities, all 8 adjacent tiles are checked for laser modifier tiles. When handling laser entities, the 8 tiles one further out are also checked for laser modifier tiles. If either of those 16 tiles is outside the map bounds, an error message was printed and the tiles are ignored. The error message is removed because it's unnecessary and misleading. Placing entities near or on the map border is not known to cause any issues.
Closes#7759.
Store X value (time) for all graph entries in addition to the Y value (FPS, prediction margin etc.). The `CGraph::Add` function adds values to the graph at the current time. The `CGraph::InsertAt` function allows specifying arbitrary X values, as long as the values are inserted in increasing order.
The entries are kept in a ringbuffer and old entries are recycled when it's full. The size of the ringbuffer is configurable for each graph, as the FPS graph needs significantly more buffer because values are added more often.
The scrolling speed of the graphs is fixed by specifying the maximum size of the window of values which should be displayed. For this purpose, a parameter is added to the `CGraph::Scale` function to specify the size of the window which should be rendered in the `CGraph::Render` function. For the FPS graph only the last second is rendered, so small spikes are still noticeable. For prediction and gametime margin graphs the last five seconds are rendered, which should result in a similar scrolling speed as before this change. The debug tuning graph is a special case, where the X values set manually and fixed to 0-127, same as before, instead of being based on the current time.
The graph rendering is made much more efficient by precalculating when the vertex colors need to be updated, to avoid all unnecessary calls to `SetColorVertex`. Additionally, line items are bundled together in an array to avoid calling `LinesDraw` for every individual line item.
Center the resize (V/H) cursors on the mouse position instead of aligning the top-left with the mouse position. This feels better to use and is consistent with the behavior for example on Windows.
Fixed crash when runing tool 'Remove unused envelopes' and trying to undo the addition of an envelope (#7738)
Fixed issues where undo/redo would not work properly when changing a layer's order or group property
Added missing action for changing the position of a sound source
The `CTextCursor::m_LineCount` variable is only updated after the cursor is rendered. For calculating the selection quads we need to check `LineCount` instead, which is updated while the cursor is being rendered. Regression from #7733.
Use yellow-orange star icon to mark favorite servers in the server browser instead of using the heart icon. The heart icon is now only used for servers with friends.
Tweak color of the star icon used for skin favorites so it's slightly more orange instead of pure yellow.
Free up space for up to three more server browser tabs of the same size (on 5:4 resolutions), i.e. tabs for configurable communities.
Remove the additional server browser icon tab on the right side. Remove the purely visual Demo and News tabs which were only shown when the respective page is already active. Instead, always show all server browser tabs when offline.
The `IClient::Disconnect` function is always called at the beginning of the `IClient::Connect` function. The `IClient::Disconnect` function calls `IClient::DisconnectWithReason`, if the client is not already offline, which performs cleanup of temporary commands and demo recorders already, so the same cleanup in the `Connect` function is unnecessary. An assertion is added to ensure that the client was properly disconnected before connecting. Connecting while the client is already quitting or restarting is now prevented, as the client state cannot be changed once set to quitting or restarting.
By adding `CDataFileWriter::ECompressionLevel` to replace usage of zlib internal compression levels in the `CDataFileWriter` API.
Use `std::numeric_limits<int>::max()` instead of `INT_MAX` in one case where the latter was only declared by the transitive zlib include. The `limits` header is already included and its use is more fitting for C++ code.
The server community was only initialized when receiving server info. This caused servers for which no server info is received to be hidden when using the community filter. Now the community filter also works correctly for servers for which no ordinary server info is received, by initializing the community already when adding server entries to the list.
Closes#7776.
Adapt the `CDataFileReader::GetItem` function so it optionally also returns a `CUuid` for UUID-based map items, including for items with unknown UUIDs where the item type will be `-1`. Adapt the `CDataFileWriter::AddItem` function so it optionally also accepts a `CUuid` which will be used if the item type is `-1`.
The additional checks for invalid map item types in the map tools are removed again and instead the new UUID parameters are used so map items with unknown UUIDs are written back to maps correctly.
Closes#7701.
Files were not being truncated on Windows anymore when using `io_open` with `IOFLAG_WRITE` due to a regression from #7254. Instead, the existing file contents were kept and the file pointer was set to the beginning of the file.
This caused broken demo files to be created (#7349) when recording a shorter demo with the same filename as an existing longer demo. It also caused the map tools to produce maps with additional junk data at the end, if an existing map is overridden by a smaller map.
This is fixed by using the creation disposition `CREATE_ALWAYS` instead of `OPEN_EXISTING` with [`CreateFileW`](https://learn.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-createfilew), which ensures that a file is always created and truncated.
A regression test case is added, which fails without this change.
Add separate `IGraphics::LoadTextureRawMove` function with non-`const` `void *pData` argument in addition to existing `LoadTextureRaw` function with `const void *pData` argument. The former function takes ownership of the data and avoids copying the texture data into an additional buffer, if the texture data is already in RGBA format. Non-RGBA texture data always needs to be converted and therefore also copied.
The `LoadTextureRaw` function is split into smaller functions to share common code with the `LoadTextureRawMove` function. Alternatively to this, a flag `TEXLOAD_MOVE_DATA` could have been added to the existing `LoadTextureRaw` function, which would have required the use of `const_cast` to free the texture data.
Unset the assertion handler before shutting down the kernel (including graphics) and client. Otherwise the assertion handler itself crashes when assertion errors happen after the graphics/client have been destroyed.
The selection in the kickvote/specvote menu was reset to the first player when the previously selected player leaves or if the filter string does not match it. Now the selection is cleared in these cases, to prevent players from accidentally starting kickvotes/specvotes on the wrong player.
Remove unnecessary `static` variable. Improve readability by not nesting post-increment in another statement.
Add color palette with up to 8 colors to editor toolbar. The palette colors work like regular color picker buttons, so they open a color picker popup on click and the value can be copied and pasted with Ctrl+Right click and Ctrl+Left click respectively. Less palette colors are shown when not enough space is available (with 5:4 resolutions).
Add color pipette which allows selecting any color displayed on the screen. Selecting a color with the pipette adds the new color to the palette and shifts the other colors to the right. The selected color is also copied to the clipboard immediately. The hotkey Ctrl+Shift+C is added to toggle the color pipette, which allows using the color pipette in popups and dialogs.
The implement this, the function `IGraphics::ReadPixel` and the command `SCommand_TrySwapAndReadPixel` are added to read a specified pixel's color from the backbuffer. Like the screenshot command, this command also requires a swap operation to be performed before the correct pixel color can be read with the Vulkan backend. The `ReadPixel` function therefore accepts a pointer to a `ColorRGBA` that will be filled after the next swap operation.
Closes#7430.
Replace linear search for free sample index with free list. This brings sound sample index allocation down to constant complexity independent of the number of allocated sounds. On average the time to allocate sound samples is reduced by around 75% (843µs down to 223µs). For perspective, the time to load all default sounds on client launch is reduced by around 15ms (although this does not significantly affect launch time due to threaded loading).
The lock needs to be owned when accessing the sound voices. Calling `IsPlaying` is redundant, as the loops effectively check whether the sample is playing.
Ensure that the UI mouse position stays inside the UI screen rect. Previously, the mouse was not considered to be inside the UI screen when all the way at the right or bottom edge. This caused the map editor tooltip to not be shown when the mouse is all the way at the right side of the map editor view. This is a cleaner fix for #4553 which reverts the previous workaround from #6423.
Add dropdown menus for changing animation and grid settings (i.e. animation speed and grid size) instead of conditionally showing more buttons for this directly in the menu bar. This frees up space in the menu bar, which is currently full on 5:4 resolutions.
The icons previously used for the default animation/grid buttons are now used for the main buttons that toggle animation/grid instead of using text.
Support setting lower animation speeds with the plus and minus buttons by adjusting the step size when the animation speed is low.
Support setting arbitrary animation speed by text input.
Render one quad for each line of the text selection instead of rendering one quad per selected character.
This increases the average FPS when the console is open and all text is selected by around 10% (from around 849 to around 943 FPS) (on my machine, in release mode).
When normalizing color components in the engine graphics, round the components to the nearest integer instead of rounding down. Otherwise the color that is rendered in color pickers may be off by 1 in any of its RGB components from the color that the color picker displays as text (hex string and individual components). The slightly incorrect color can be confirmed by creating a screenshot or otherwise reading the backbuffer (planned editor pipette feature).
This should not change map rendering, since maps already store quantized RGBA values on which the rounding mode should have no effect. It may however slightly change appearance of colors in all other places (at most +1 in every RGB component).
The individual color components were rounded down when being displayed on their own in color pickers, whereas the components are rounded to the nearest integer when packing the colors into the hex string. This was causing minor discrepancies between the color being displayed/saved as hex and the individual components. Rounding the components when packing is necessary to reduce the error when converting between color spaces.
Add tabs to player and tee settings pages to switch between player (main) and dummy settings instead of using a checkbox for this, to improve the usability.
Improve layout of tee settings page, especially with 5:4 resolutions, where the eye selector previously overlapped with other UI elements. Decrease size of eye selector and make better use of empty space overall. Use more space for skin selector instead of showing empty space when "Use custom colors" is disabled.
Show favorite skin buttons also when hovering list items to make it easier to discover the feature. Add small highlight color to favorite skin buttons when hovering them.
The text color was previously set and reset for every individual number being rendered for non-empty tele, speedup, switch and tune tiles. The color is the same for all tiles from each entities layer, so most of these `TextColor` calls are unnecessary. Now the text color is only set and reset once when rendering each entities layer.
Let's say you have this bind:
```bind x +toggle cl_dummy_hammer 1 0```
and you set cl_dummy_control to 1.
When you press the bind i mentioned above, and then release, the dummy will hammer where he is looking (not at you). So, in total, there will be two hammers. One hammer when you press down the button and the dummy hammers towards you, and then another hammer when you release the button and the dummy hammers where he is looking.
This fixes it, and also makes sure it does not conflict with cl_dummy_copy_moves (as if it is enabled and cl_dummy_control is enabled, the dummy will not copy fire, hook, or jump) so I made sure it keeps this functionality as it's pretty cool.
This does not fix any other bugs yet, maybe I will fix those in the future but we'll see. Any bug you may encounter with this change is also probably present in the main branch, such as resetonswitch not working perfectly with dummy_control, but if you do find something different then let me know.
According to the Vulkan specification, the struct `VkBufferImageCopy` is used only for `vkCmdCopyBufferToImage` and `vkCmdCopyImageToBuffer`. The variable `Region` is only initialized but not passed to either of those functions.
- Use existing functions from `system.h`
- Use sorting from `<algorithm>`
- Don't recall `ListDirectory` for every removal, which caused the client to hang previously with a lot of files.
Consider line spacing to belong to the previous line when calculating and rendering text selection. Instead of handling spacing between entries separately in the console, also include line spacing for the last line in the height calculation. Pixel align the line spacing in addition to the font size, as previously some gaps between the entries were larger than others due to missing pixel alignment. This allows rendering the text selection in the console smoothly without any gaps between the console entries/lines.
Closes#7617.
Reduce duplicate code.
Replace `clampf` function with `NormalizeColorComponent` function that convert color component from `float` to `unsigned char`.
Use `size_t` instead of `int`.
The `mem_copy` function does not respect zero termination so it reads beyond the size of the source buffer, if it's smaller than the destination buffer.
Favorite skin names were previously not escaped as intended when saving, as the variable `aNameEscaped` was unused so the original skin name was saved instead of the escaped one. Escaping is not really necessary, as skins should not contain `\` and `"` anyway and it was only possible to add such favorites through the console or config files. Instead of escaping the favorite skin names when saving, now favorite skin names are validated when they are added so no escaping is necessary. Skins names are considered valid when they have a length of 1-23 bytes and don't contain the characters `/`, `\` and `"`.
All `map_*` tools were crashing with the assertion `Invalid type` when used on maps that contain unknown UUID-based map items. When the UUID cannot be resolved, the type `-1` is returned by the `GetItem` function. The assertion predates UUID map items, so this crash has likely existed since the introduction of UUID map items. The editor was not affected and has instead always discarded map items that it does not support. The tools will now also discard map items with unknown UUIDs.
See #7669.
The current mouse-based console selection was not being adjusted anymore when new lines are added to the console, as the `m_NewLineCounter` variable was decremented to `0` before the relevant check for `m_NewLineCounter > 0`.
The selection is only cleared because it would be incorrect after scrolling, but it doesn't need to be cleared if the scroll position does not change, e.g. when pressing Home while already at the top of the backlog.
