Comment 99 for bug 291053

Correction of my previous statement. On Fedora 12, with:
mesa-libGL-7.6-0.13.fc12.x86_64
mesa-dri-drivers-7.6-0.13.fc12.x86_64
mesa-libGLU-7.6-0.13.fc12.x86_64
mesa-dri-drivers-experimental-7.6-0.13.fc12.x86_64
I do see corruption even when DRI is enabled:
OpenGL vendor string: Advanced Micro Devices, Inc.
OpenGL renderer string: Mesa DRI R600 (RV740 94B3) 20090101 TCL DRI2
OpenGL version string: 1.4 Mesa 7.7-devel

However, I need to actually use Compiz (or probably some other 3D app) to actually make it start occuring; it will happen in less than half an hour.

When I don't use a 3D app, and DRI is enabled, corruption will not occur for hours (and probably never, but I can't test that hypothesis :-D ).
