Feel free to redirect me if not, even to /dev/null. The Video(DRI - Intel) section on kernel bugzilla doesn't seem to get much life.

Hi Emil,

Thanks for your interest and report on Xe bugs.
Please follow this link instead: https://drm.pages.freedesktop.org/intel-docs/how-to-file-i915-bugs.html

The entire dmesg would be needed to help us to understand what's going on here. From the pasted
portion below it doesn't even look like xe is in the picture.

But only more details could help to determine what's going on. Also, keep in mind that Xe,
specially for BMG, was in very active development and a lot might have changed since 6.12.
So, it would be great if you could run some experiments with newer kernel as well.

Thanks,
Rodrigo.

VS Code was not running on XWayland. So far I haven't been able to reproduce this. I have amdgpu loaded as a fall back for my ryzen 7900X builtin graphics since I installed the funny GPU (Intel Arc B580 / BMG G21). I'm on Mesa 24.3.3.
