  SQUASME: Address review comment

• PatTheMav(18 Aug 26)

  Update codestyle document Clarifies language around thread-safety of function-local static variables. Since C++11 these variables are initialized in a thread-safe way (no concurrent initialization), but this guarantee does not extend to consecutive accesses to that object (which would still need to use a thread-safe internal implementation if necessary).

  Update contribution guidelines for PR reviews Adds guidelines for pull request reviews particularly around requesting reviews and how to handle review threads: * Only project members are allowed to request reviews from specific users. * Only reviewers are allowed to resolve review comment threads, only project members can unilaterally resolve them if reviewers are unresponsive. * Reviewers should thus take care to check for updates and resolve their comments if they have been addressed. * Pull requests authors should try to avoid force-pushes and rebasing their branches to a minimum to make it easier for reviewers to track changes during review.

  frontend: Use styling for source items appearance The icon and text label for items in the source list was previously enabled/disabled based on scene item visibility state. As of Qt 6.11 Qt no longer triggers context menus when right clicking a disabled QLabel. This means right-clicking a hidden scene item would not show a context menu. Updates SourceTreeItem to use styling classes via idian helpers instead of changing the enabled state of these labels.

  frontend: Register the replay buffer save hotkey in the frontend Existing registering of the save hotkey in obs-ffmpeg makes it impossible for it to trigger a frontend event, and is inconsistent with other existing output hotkeys. This registers the save hotkey in the frontend and removes the registration in obs-ffmpeg, and adds a "due to hotkey" log message, like other output hotkeys.

  libobs: Change canvas signal param name to `signal_canvas` Just a nitpick, as `signal_source` is a copy/paste from obs-source

  libobs: Fix monitoring hotkey UI updates Send the monitor signal first because initializing compat_data overwrites the same buffer, causing the monitor value to always be false.

  win-capture: Add Construct 3 window class to WGC match Construct 3 games register a top-level window class named "WindowsWebview2Wrapper" which does not contain "Chrome" or "Mozilla", causing OBS automatic mode to use BitBlt instead of WGC, which results in a black screen for Construct 3 games. Add "WindowsWebview2Wrapper" to wgc_whole_match_classes and add compatibility entries for window capture BitBlt and game capture warnings. Closes #13359

  obs-ffmpeg: Fix B-frame offset calculation in AMF AVC and AV1 encoders in AMF that support B-frames were incrementing `dts_offset` even when B-frames were set to 0. For AVC, adjust the `dts_offset` only when B-frames are supported and are greater than 0, and clamp to maximum supported. For AV1, remove the dts_offset code completely because it is being ignored anyway. AV1 handles B-frames and offsets differently; refer to [1] for details.

  libobs, docs: Document intended use of obs_module_unload obs_module_unload was never properly documented, so some plugins use it to free resources, some use it to save data, etc. While libobs tries to ensure all objects are shut down and destroyed before calling unload, if another plugin is holding a strong reference, or if a reference leak has occurred, libobs may need to call back into a plugin-provided object's destroy function even after obs_module_unload has returned. If the plugin has freed memory or other resources needed for the callback then this likely results in a crash. Going forward, we should document that obs_module_unload is now intended only for saving data and releasing references, and that calling libobs after it returns is not allowed. For cases where resource cleanup is actually needed (for example, an external out of process helper needs to be shut down or a release call to a hardware driver), a new obs_module_destroy callback is intended to be added in a future version.

  win-capture: Improve fullscreen window detection It's not that uncommon for apps on Windows to use a hacky method of extending their windows 1-2px past the supported monitor resolution to preserve "true" windowed fullscreen and circumvent some exclusive fullscreen-related issues presented by their graphics library, Windows itself, or both. Therefore, the fullscreen detection technique has been relaxed to properly identify windows slightly larger than the monitor's viewport as fullscreen. Windows also does something similar, evident by the fact that the taskbar disappears, as it always does for fullscreen windows, even when a window stretches slightly beyond the defined viewport.
