Comment 6 Nate Graham 2025-12-09 16:17:16 UTC 
This is the #5 Plasma crash right now; raising priority.

The error message suggests that it may be a compositor issue, so I'm moving this to KWin for further triage.
Comment 7 Vlad Zahorodnii 2025-12-11 11:31:15 UTC 
Can somebody run plasmashell with the WAYLAND_DEBUG=1 environment variable, make plasmashell crash and attach the logs to this bug report?

   WAYLAND_DEBUG=1 plasmashell > log.txt 2>&1
Comment 8 Vlad Zahorodnii 2025-12-11 11:32:11 UTC 
You may need to stop the existing plasmashell instance before running that command, i.e.  `systemctl stop --user plasma-plasmashell`

I'm not running any command, only happens when my computer wakes from sleep or monitor off state.
Comment 16 M. Schulte 2025-12-19 15:44:24 UTC 
I have the same problem, and I have been trying to get a log for this kind of crash for days, unfortunately without success. It seems that when I restart plasma with WAYLAND_DEBUG I just can't get it to crash. And on days where I forget to restart plasma with debug output I run into the problem again. I only tried for a few days so it could just be by chance, but it almost seems like the problem just does not show up if I start plasma manually.
Unfortunately the problem isn't very reproducible for me in general but I'll continue trying.
Comment 17 M. Schulte 2025-12-22 16:40:45 UTC 
Created attachment 187875 [details]
WAYLAND_DEBUG=1 output of plasmashell during crash

Added WAYLAND_DEBUG=1 output from crash. Removed anything before the screen locking and after the crash though for privacy reasons.
