I've had corruption for quite a while, it seems to be made worse
under memory pressure, and when using opengl style apps (firefox,
chrome, prusaslicer, openscad, etc) - usually in the form of mostly
black blinking rectangles filled with a few flashing mostly red lines.
It's annoying, and will happen over any app (xterm, even xroot).

I'm pretty sure I saw this with 9.x. Currently 10.1, amd64, with
i965 on SNA Sandybridge (gen6, gt1) backend.
