<pre>FWIW, I tested the driver as of commit 4fdd3a7 and was still seeing the same
issues. Turns out if I run a glx program (e.g. compton), I can't reproduce the
issue. I also use awesomewm which doesn't come with a compositing window
manager, however I noticed that I wasn't able to reproduce the issue with Unity
or Gnome which both do include compositing window managers. The other thing I
noticed is that if I didn't use a compositing window manager but opened
glxgears after the screen corruption, the screen would be restored to normal.</pre>
