Screenshot of the problem
Using netbeans I stumbled over the problem, that for example the exception reporter shows distorted images, when scrolling to the right. Scrolling left redraw the image correctly. I build a minimal example programm, that exhibits the problem (will be attached in source and compiled as TestApp.tgz and TestApp.jar).
Scrolling a few time right and left lead to the attached wrong.png.
I'll attach xorg.conf and Xorg.0.log as attachments with wrong_ prefix.
I tested with disabled acceleration (Option "NoAccel" "true") and there now text distortion is visible (see the ok_ prefixed attachements for mor info).
This is ubuntu 12.04 running with the xorg-edgers repository.
The xserver-xorg-video-radeon package version is: 6.14.99+git20120605.4603285a-0ubuntu0sarvatt~precise
