Forwarding this bug from Ubuntu reporter unlive: http://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-ati/+bug/761998 [Problem] Bad corruption in the form of line noise shows up in both the launcher and dash in Unity, which appears to only occur on -ati with certain hardware (the HD 3450 at least). Unity developers indicate they believe this is corruption in -ati / mesa rather than in the compiz rendering code.

This is probably a 3D driver bug. Are you using r600c or r600g? Possibly related to bug 36442.
r600g OpenGL vendor string: X.Org OpenGL renderer string: Gallium 0.4 on AMD RV620 OpenGL version string: 2.1 Mesa 7.10.2
Any suggestions on what else could be tested?
Created attachment 55636 [details] artefacts under -nouveau This appears to happen in -nouveau too. Screenshot attached. What additional information do you need? I'm running xorg-edgers PPA versions of everything on Ubuntu.
Is this still an issue on newer versions of r600g?
Closing due to lack of feedback.
