So newer graphics, Vega56/gcn5 compared to my gcn4.

No VMs at all here so that can be excluded as a factor (unless it's a minor
trigger similar to my zooming or video play).

KDE/Plasma here too.  I think kwin exercises the opengl a bit more than some
WMs, in part because it's a compositor as well.  The bug most often hits here
when playing video or using kwin's zoom effect, which exercise the graphics a
bit.

So mostly kde/kwin triggers could lower the population hitting it and could be
a factor, based on both of us running it.

Newer graphics, gcn5 to gcn4, older cpu, phenom ii to fx, than here.

So we know gcn4 and gcn5 are affected, and pcie2 bus with pcie3 cards and
kde/kwin are common-factor possible triggers so far.

If you happen to run anything besides KDE/Plasma on X, duplicating (or failing
to duplicate) the bug on non-kde and/or on wayland would be useful info.  I
only run KDE Plasma on X here.  Well, that and CLI (on amdgpu-drm-framebuffer)
more than some but not enough that I'd have expected to see it there, which I
haven't.
