SUMMARY
I'm using Arch Linux as my daily drive. I updated my system just now and reboot. But I got black screen. I got into TTY and found out that the kwin_wayland SIGSEGV crashed, which resulted in SDDM cannot display normally.

STEPS TO REPRODUCE
I'm not sure if there is a way to reproduce the crash stably.

OBSERVED RESULT
kwin_wayland crashed and SDDM cannot display its content.

EXPECTED RESULT
kwin_wayland runs normally.
