SUMMARY
I am using an nvidia gpu with wayland. When I try to logout instead of
returning to sddm the desktop restarts and I can no longer click the log off
button (https://bugs.kde.org/show_bug.cgi?id=449948).
The problem does not appear when using the X11 session.
Backtrace:
Core was generated by `/usr/bin/kwin_wayland --wayland-fd 7 --socket wayland-0
--xwayland-fd 8 --xwayl'.
Program terminated with signal SIGSEGV, Segmentation fault.
