-- Information about the crash:
I usually leave my system running over night. It's configured not to sleep, but just to turn off the screen after a few minutes. No lock screen or anyhting similar. For the past two or three nights now, I will wake up to a KWin crash every morning.

The crash can be reproduced sometimes.

Comment 3 TraceyC 2025-08-25 20:18:10 UTC 
Thank you for the bug report. Based on the backtrace this looks like a duplicate of bug 504959. This was fixed in Plasma version 6.4.5. The fix will reach your system when it updates to that version.
