I have now compiled and tested a 3.6.kernel to match the commit immediately before the "mega commit", i.e. the kernel tarball has been produced by the following command:
Unfortunately, I am unable to test whether the screen distortion issue occurs with this kernel, because I get a complete hang (system freezes, CPU and GPU fans running full speed) somewhere between some seconds and some minutes after starting GNOME...
Note that I have seen both: either no screen corruption at all or first slight signs of screen corruption (white rectangles around window frames) at the times of the hangs.
The error messages that I find in /var/log/messages probably associated with the hangs (sorry, I can't get any messages ot of dmesg due to the hang...) seem to be the following:
[drm:drm_mm_takedown] *ERROR* Memory manager not clean. Delaying takedown
[drm:drm_mm_takedown] *ERROR* Memory manager not clean. Delaying takedown
[drm:drm_mm_takedown] *ERROR* Memory manager not clean. Delaying takedown
repeating any number between 3 to 5 times directly before the hangs (immediately followed by /var/log/messages starting over with my power-off machine restart).
Will now move forward to test with the most recent stock kernel from the 3.6 series: 3.6.11-3.6.y.20121225.ol6 from the Oracle public yum playground to see whether this already is affected... :-(
Hmm - bad news once again:
