SUMMARY
STEPS TO REPRODUCE
1. Start a video in a workspace using a method of your choice that uses video
hardware acceleration on intel. You should be seeing Video/VideoEnhance being
active on intel_gpu_top. I've tested it with mpv, vlc, chromium, Firefox.
2. Change to another workspace
3. Wait for a bit
OBSERVED RESULT
Video running in the background stops/becomes extremely choppy.
EXPECTED RESULT
Video playing normally.
SOFTWARE/OS VERSIONS
Windows:
macOS:
Linux/KDE Plasma: Wayland 6.0.4, Endeavour OS
(available in About System)
KDE Plasma Version: 6.0.4,
KDE Frameworks Version: 6.1.0
Qt Version: 6.7.0
ADDITIONAL INFORMATION
You can work around the bug by either switching to a tab in the browser that
does not play video or in mpv by setting the option hwdec=auto-safe. It is not
clear if this is a wayland/intel driver or KDE bug.
