I've tested a bit more and I don't always see it when just running and
individual app. 

I have a script that runs the mesa demos in alphabetical order - and so far
running like this I have always seen it on some random selection of the 3D
demos.

fbo_firecube is often OK, but if it does show it, then the corruption will be
along the diagonal of the faces of the rotating cube and not across the window
like the others.

Openarena is the only game I've seen it with. The corrupted squares/rectangles
have varying content and also get the bloom effect applied to them.
