Hello,

I have the same error message on my laptop (no VM with GPU passthrough, just a
plain laptop :^)

In dmesg, I find these messages:

[ 1781.226890] [drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure
on pipe A (start=107045 end=107046) time 310 us, min 763, max 767, scanline
start 755, end 765

and

[ 2490.145236] i915 0000:00:02.0: GPU HANG: ecode 7:1:0xfffffffe, in Xorg
[1021], hang on rcs0
