Description of problem:
I observe massive display corruption in blender with radeon driver / Gnome Xorg
session:

The whole interface seems to blink back and forth (triggered by moving he mouse
around) between the current state and some state it had before the last
interaction. As a result, when clicking a button or doing something that
greatly changes the view, the interface will then blink back and forth wildly
between the new state it should be in and what I saw before that interaction.
Since the UI consistently reacts to the new state even when the old one blinks
in between, this seems to be purely some sort of render corruption rather than
some actual UI bug.

How reproducible:
100%, just launch blender and click something to trigger a UI state

Steps to Reproduce:
1. Launch blender
2. Change the view / open a file / rotate the view / ... do anything that would
require the UI to change

Actual results:
UI and views update correctly

Expected results:
UI and views update but blink back and forth with older previous state

For what it's worth, this effect is always limited to purely the contents of
the blender window itself. So it doesn't seem to be the gfx driver freaking out
as a whole, but some blender-related problem.
