Bug ID: 443493
Summary: Certain windows or menu entries "stick to" the screen
and cannot be removed without replacing kwin_x11
Product: kwin
Version: 5.22.5
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: compositing
Assignee: kwin-bugs-n...@kde.org

Ugly Xorg crap (context menu) covering active window
SUMMARY
I keep using my PC normally. Then I close any program. Suddenly, kwin goes mad
and the window "sticks to" my desktop with slightly lower opacity. It remains
on top of other windows too.
STEPS TO REPRODUCE
1. Use PC normally
2. Close any program
3. Sometimes, the closed window "sticks", sometimes it doesn't
OBSERVED RESULT
See attachment. A "sticky" context menu is covering KRunner. Also happens with
other windows (both KDE & non-KDE apps)
EXPECTED RESULT
The context menu shouldn't "stick" in the first place
SOFTWARE/OS VERSIONS
Windows:
macOS:
Linux/KDE Plasma: 5.14.9-arch2-1
(available in About System)
KDE Plasma Version: 5.22.5
KDE Frameworks Version: 5.86.0
Qt Version: 5.15.2+kde+r237-1
ADDITIONAL INFORMATION
The bug is irregular though, like only 1-2% windows "stick" like that. Also
it's not yet reproduced in Wayland. May also be an OpenGL or Xorg bug, but I'm
a noob and Xorg source code on freedesktop seems spooky, so can't confirm that.
