Mutter (the compositing manager for GNOME 3) is an excellent way to cause GPU hangs. The following hang was caused by running Mutter and OpenArena, but pretty much any gl app more advanced than glxgears will cause a hang when Mutter is used.

This was a regression in 0f328c90dbc893e15005f2ab441d309c1c176245
as mutter repaints the whole screen every frame, so it'll tend to hit the working set > aperture case earlier than, say, compiz.
