** Description changed: + Bug is being tracked upstream: + https://bugzilla.mozilla.org/show_bug.cgi?id=2083269 + High/Random frame drop when playing video on Wayland: 1. Frame drop count seems to be related to number of open tabs and installed addons 2. Disabling "widget.wayland.vsync.enabled" significantly reduces the dropped frame count on youtube player "stats for nerds" but the actual/visual frame drop remains the same. On some systems (probably newer/faster) actual/visual frame drop is less noticeable 3. Running with "env GDK_BACKEND=x11" or on X11 session resolves the issue 4. Testing was done with default youtube codec "VP9". The test system doesn't have VP9 hardware decoder 5. Both Snap and Mozilla .deb are affected 6. Tried various other solutions and configurations but nothing helped 7. Tried fresh firefox and OS user profiles 8. Video resolution makes no difference Test system: --- Firefox version 156.x -> 158.x Operating System: Kubuntu 26.04 LTS KDE Plasma Version: 6.6.6 Processors: 4 × Intel® Core™ i7-6560U Memory: 16 GiB of RAM Graphics Processor: Intel® Iris® Graphics 540
