Does the problem go away with the Mesa master branch?
Nope. It makes no difference. The problem has actually gotten worse since I got the updated packages I listed comment #8 vs the original report. And the issue stays the same with Mesa master branch from today.

Anyhow, attempting to enable any sort of compositing (aka desktop effects) in kwin results in a completely black window ontop which are some rectangular colored (green/red) artifacts. The 3D game is about as usable as it was in the attached screenshot.
