I'm not too familiar with GDB. Can you give me some instructions on what to do exactly?

Yeah I was also considering the driver to be the issue. Especially since I recently update to a newer version. But a rollback to the previous version also didn't fix it yet. I'll try out your suggestion! ... Yeah that seems to work for me. Thanks for the idea!
Not so sure what the learnings are from this issue here. I guess I have to wait until it's fixed in the amdvlk drivers.
Sorry for the trouble right before the release. I'm closing this.

2023.Q4.2 of the amdvlk driver and I thought that was the issue2023.Q4.1
I did check out discord and the existing issues and I think this hasn't been reported yet. Feel free to close it, if I oversaw something.

I did intend to try out some new features on main and ran a few examples on the mentioned commit. Just to name one: the
clear_colorexample.What went wrong
All of the examples which are graphical in any way seem to segfault with
There's not even a window popping up before the app crashes.
I tried to verify it isn't my setup by running the same examples on the latest release tag (
v0.13.2) and everything worked fine there.Additional information
