Re: KDE 6.6.1 update - Xwayland problem
It seems that login to X session and then login back to Wayland fixed this trouble

Re: KDE 6.6.1 update - Xwayland problem
I guess you just updated mesa?
The re-login was probably more important than the interim X11 session.
Please always remember to mark resolved threads by editing your initial posts subject - so others will know that there's no task left, but maybe a solution to find.
Thanks.

Re: KDE 6.6.1 update - Xwayland problem
After update to 6.6.2 it has completely broken. Re-login X11 or Wayland session does not help anymore

Re: KDE 6.6.1 update - Xwayland problem
What does "completely broken" mean?

Re: KDE 6.6.1 update - Xwayland problem
I suppose the backtrace in the OP.
@cdiamond, that's an abort, there's most likely some message in the system journal accompanying it.
Also https://wiki.archlinux.org/title/Debuginfod might help.
