Comment 1 Nate Graham 2025-03-28 14:34:22 UTC

Thank you for the bug report! Unfortunately I the backtrace is incomplete and missing debug symbols for all lines that we need to figure out exactly what's going wrong. Could you please install debug symbols and attach a new symbolicated backtrace generated by using `coredumpctl gdb` in a terminal window? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl for details about how to do this.

Thanks again!

Yes, I'm aware this backtrace isn't useful, I'm working on getting one that is.

Comment 3 Shawn W Dunn 2025-03-28 16:02:22 UTC

Here's the best I've been able to get, after installing about 200 debuginfo packages.

Thanks!

Looks like it's crashing in your graphics drivers, unfortunately. If you can get debug symbols for Mesa, I'd recommend reporting a bug. See the instructions at https://docs.mesa3d.org/bugs.html
