Bug ID: 501665
Summary: Hang when going into fullscreen with jellyfin
Classification: Plasma
Product: kwin
Version: 6.3.3
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
Whenever I play something with Jellyfin and enter fullscreen, the screen
freezes. Pressing keys and audio still work, but the screen is completely
frozen. It only happens if I use Wayland and Fractional scaling. It doesn't
happen with Gnome or X11.
Using kernel 6.11.4 and Mesa 24.2.8 doesn't help.
