Package: firefox-esr Version 140.3.1esr-1~deb13u1 amd64 When Recommended Performance Settings are enabled, video playback will occaisionally show graphical glitches. Sometimes this will be fixed by reloading the tab, but sometimes it will crash the Wayland session and go to the GDM login screen or a command prompt.
This does not happen when Recommended Performance Settings are disabled but Hardware Acceleration is enabled.
