Hi, We have a bug report in blender3d on linux which reports a drawing problem
with both Intel and ATI graphics cards (32 and 64bit x86 - linux).

I didn't get the problem with me nvidia driver so I compiled the latest mesa
(7.8.1) and ran blender with Mesa's software libGL.so LD_PRELOAD'd to redo the
bug.

I made a simple example of this bug in python (depends on pygame and pyopengl)
to show how this bug happens in an isolated testcase.

See attached, will attach an image of the bug next.
