Bug ID: 512902
Summary: Bypassing compositor incorrectly affects other windows
Classification: Plasma
Product: kwin
Version First 6.4.3
Reported In:
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: compositing
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
Possibly a duplicate of https://bugs.kde.org/show_bug.cgi?id=361091. I'm not
sure.
Running an app that bypasses the compositor seems to break something with how
other apps interact with compositing
STEPS TO REPRODUCE
1. In settings, disable Display and Monitor > Compositor > Allow Applications
to block compositing
2. Run an app such as Firefox
3. run mpv --x11-bypass-compositor=yes path/to/video.mp4
OBSERVED RESULT
Firefox windows have a thick black border around the window for the duration of
the video. Other apps with transparent backgrounds lose their transparent
background.
EXPECTED RESULT
Other windows are not affected - only mpv.
