This only happens on Wayland session, doesn't happen on Xorg.
Comment 2 David Edmundson 2024-01-12 18:00:10 UTC 
Do you have a backtrace?

> Do you have a backtrace?
For some reason there's no core dump in coredumpctl for that segfault. Is there a way to get core dump for kscreenlocker_greeter that starts when I enter suspend?
