Anything else needed?
Tried with cdimage:
Still very ugly glitches!
Please, if I can provide any more details or something, tell me!
I added a glxinfo output again of the version of the used libgl stuff.
Anyway, as it was the livecd boot, I can reproduce it very easily.

Does the attached kernel patch fix the issue?
A patch referencing this bug report has been merged in Linux v3.9-rc4:
Author: Alex Deucher <firstname.lastname@example.org>
Date: Mon Mar 11 19:28:39 2013 -0400
drm/radeon: fix backend map setup on 1 RB trinity boards
Finally I found some time do reinstall Ubuntu and compile the kernel with the patch. Sadly it doesn't fix the issue. :(
Forgot to mention, which versions I used.
The Ubuntu I installed was raring latest with selfcompiled kernel 3.8.4 (from http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-raring.git).
Does disabling tiling help?
Option "ColorTiling2D" "false"
in the device section of your xorg.conf?
Do you think, the Kernel patch fixed something which works together with the tiling option. If not, we tried this already last year (Nov.)
But I will give it a try.
I tried both with the patched kernel, only ColorTiling2D and ColorTiling plus ColorTiling2D.
The glitches still occur.
Any other ideas?

Does this kernel patch fix the issue?
Sadly I must say, that this patch changes the behave in no way, too. :( ...
It's still flickering and showing theses glitches as in the video.
Could I add any debug output, any printks which would help to identify the problem?
Anything else I should test?
Currently I'm testing on raring latest with following kernel + the two patches mentioned in this thread.
The first is already part of the kernel, so it's the kernel + the second patch.
Any news about this prob? Any questions? Additional Info needed?
I updated to ubuntu raring latest again and the bug is still bugging me ;).
Please let me know if I can provide more info so the bug can be fixed.

Does this patch fix the issue?
Sadly no. Unity still is flickering and has that triangle kind of display errors.
