In fairness, distros do include their own patches, and it's possible that there is some regression that showed up somewhere above 6.12 and he's running a vanilla kernel and the Arch guys put in some patch that fixes whatever he's seeing that isn't in vanilla or something. Or maybe he's using a distro that includes some kind of kernel patch that introduces the problem, if he's not building his own kernels. I mean, I've got no idea what the guy is running; he doesn't say.

Well when the crash happens and the screen shows an enormous amount of green artifacting, sure looks like a graphics driver and/or kernel issue to me. But yeah, I'm probably wrong because your experience is pristine. And the many hours of research I've done on this subject leads to the conclusion that there are issues with 6.13+ kernel, amdgpu driver, and Wayland, and especially if having more than one display connected (despite setting the refresh rates to the lowest common denominator).

But I'm sure I'm wrong and it's something completely different. Thanks for the insight.
