Comment 2 fanzhuyifan 2023-12-22 05:39:42 UTC 
It seems that your kwin_wayland dumped core. Could you provide a backtrace with debug symbols following the instructions here? https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl

Thanks!

Comment 7 fanzhuyifan 2023-12-22 06:07:02 UTC 
So I think the kwin one is the important one here. Currently the backtrace doesn't seem complete.

You will need to do something like `sudo chown ...` or `sudo chmod` to give yourself permissions to read that file.

Also, your backtrace are missing debug symbols. Unfortunately I don't think the garuda linux folks are providing that for kde-git (correct me if I am wrong). So to get a backtrace with debug symbols, I guess you either have to build from source, or try to reproduce this on neon unstable. Or you could try asking the packagers of your distribution to provide  debugging-enabled packages.

Comment 9 Derek Graham 2023-12-22 08:25:33 UTC 
I installed the Unstable Neon and same thing on there

(In reply to Derek Graham from comment #9)
> I installed the Unstable Neon and same thing on there

Would you be able to provide the backtrace with debug symbols there?

Again you probably need to change the permissions of the core dump file. You will need something like 
export DEBUGINFOD_URLS="https://debuginfod.ubuntu.com"
for debuginfod to work. If you are asked Enable debuginfod, please select yes.

See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports for details

Thanks again!
