Description Michael Hamilton 2024-03-29 03:54:07 UTC
I used desktop->right-mouse->Lock Screen on latest KDE6, X11, Nvidia 550.  I noticed plasmashell coredumped during the lock.  After unlocking the panel and kwin window decorations were missing.  I had to telinit 3 and telinit 5 to get back to a login.

I did a "coredumpctl debug" on the most recent core dumps:

------------
Core was generated by `/usr/bin/plasmashell --no-respawn'.
Program terminated with signal SIGSEGV, Segmentation fault.

warning: Section `.reg-xstate/4509' in core file too small.
