Bug ID: 454843
Summary: kwin_x11 --replace now makes it 1 FPS
Product: kwin
Version: 5.24.90
Platform: openSUSE RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: platform-x11-standalone
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
After the update to Plasma 5.25 beta, if I run "kwin_x11 --replace" in the
terminal, the KWin instance that launches make windows redraw and move what
feels like one frame per second. The cursor moves smoothly. The resource usage
stays normal. Running "killall kwin_x11" makes windows draw fast as expected.
Only a reboot gets me back to a normal KWin, though.
The only time I've seen this symptom before was due to the 3rd-party Parachute
effect:

— but I haven't used it since.
STEPS TO REPRODUCE
1. Open Konsole
2. kwin_x11 --replace &
OBSERVED RESULT
A slideshow
EXPECTED RESULT
KWin running normally
