Yes, there's also https://bugs.freedesktop.org/show_bug.cgi?id=109955.
To be honest, I couldn't say if my issue is the same as either of
these -- I wouldn't know where to begin to interpret these logs, or
even say whether they're essentially showing the same or something
completely different. From experience, blindly lobbing stuff together
because of the first error message that pops out is dangerous. That's
why I'm asking here.

Shouldn't that mean that more demanding games crash more often?
Neither Ori nor CK2 are likely to tax a Radon VII, at least temps stay
down, and so do the fans. I remember a single crash from Overcooked
[Proton/DXVK], same; but none from Prey (2017) [Proton/DXVK] or Life
is Strange - Before the Storm [native Vulkan]. That said, I mostly
play games one after the other, just because something didn't crash
then, that doesn't mean it wouldn't now.

> Also, some Reddit users pointed out all these games are Vulkan based. It could be a Vulkan specific issue.

I'm running Ori using WINED3D (D3D-OpenGL), CK2 is native OpenGL
AFAIK, that hypothesis doesn't hold.

The various search results that look similar to the layman also offer
a plethora of workarounds, a lot of which look to be of the sacrifice
a chicken at full moon and dance around it counter-clockwise intoning
sea shanties at the top of your voice variety to that same layman.
Understandable, when you don't know if it helped or the bug just takes
particularly long to trigger. I'd still rather help identify & fix the
root cause.

Thank you for caring.

Cheers,
C.
