I still see occasional flickering and corrupted squares on both me and my
mother's computers, both running openSUSE Tumbleweed and AMD video cards but
obviously different hardware. Even when changing video cards, the issue will
more or less persist just happen at different stages. Sometimes it's just an
annoyance that goes away quickly, at other times desktop effects or even the
whole computer must be restarted because the graphical corruption covers the
entire screen and you can't see anything any more. It also happens with both
'radeon' and 'amdgpu', the problem is not exclusive to any one driver.

This is clearly something deep in the core renderer code or AMD drivers which
has been going on for a long time now. I'm pretty surprised it's not being
discussed a lot more often, since from what I'm seeing it's something thousands
of users should be able to easily confirm.
