SUMMARY

Sometimes, after moving or resizing another window, they glitch out like they're still being moved/resized. After closing or minimizing them, they keep rendered at the screen, sometimes overlaying other windows, although they're inactive and the system ignores them and input events works normally.
Logging off and relogin doesn't fix the issue, the system freezes (only when this occur), only rebooting fix the issue.
The time it occurs and wich app is random, anything can get randomly affected by this issue and it keeps spreading after the first glitch

Comment 1 Josesk Volpe 2021-08-16 01:05:05 UTC

Expected behaviour:
Window always closes and minimizes normally as expected. Overlayed frames disapears.

Actual Behaviour:
Closed and minimized windows remain visible sometimes and won't go away, overlayed frames too. Animations are played normally but the window returns after the animation finishes

Addedum #1
I disabled transparency as requested in this thread: https://forum.kde.org/viewtopic.php?f=111&t=151833

Windows and frames that were closed but glitched and remained visible were closed after disabling transparency effect
