kwin_x11 causing high cpu usage on Wayland session
SUMMARY
Sometimes my cpu fan rotates faster immediately after logout, then I noticed
that when such behavior occurs plasmashell or kwin_x11 process is stuck in
memory and causing high cpu usage.
Please see the attached screenshots showing kwin_x11 and plasmashell causing
high cpu usage on Wayland session. I can't reproduce this problem consistently
though.
STEPS TO REPRODUCE
1. boot your system
2a. start and restart X11 a few times (at some point kwin_x11 will get stuck in
memory after logout)
2b. start and restart Wayland session a few times (at some point plasmashell
will get stuck in memory after logout)
EXPECTED RESULT
kwin_x11 and plasmashell should never get stuck in memory after logout
