Could it thus be possible that RENDER acceleration "globally
struggles" the GPU so that it eventually can't process OpenGL request
correctly?

What has changed between Metacity 2.30 and 2.34 w.r.t 2D (3D?)
acceleration that could explain this issue?

I'm not sure if the lock up during the WebGL tests still appears on
the same test. If yes, I imagine it will help understand what's going
on. I'll try to have a reproduceable error.
