Bug Description
There is terrible flickering happening with the Radeon driver in Ubuntu Unity as well as gnome-shell. This flickering has been present when doing things that require 3d for a long time, and there was recently a fix that was released that is not really a fix at all.
The fix that was released only fixes the flickering for a short while after first logging in, but if you do anything graphics intensive (such as clicking the workspace switcher 5-6 times in repetition) the flickering comes back as bad as ever.
I gnome shell the flickering shows up whenever you mouse down to the lower right hand corner and have the shadow gradient come up from the bottom. The sides of any open windows will have graphical glitches. The flickering also happens in unity any time I use the workspace switcher, I open the Dash, or when I use the full-screen snap feature.
I would like to mention that I do not have any of these issues when running Arch linux, but I do in Fedora 16, but not to the extreme to which I have them in Ubuntu 12.04. I know that Ubuntu uses a custom xorg version, so perhaps there is a regression in the way Ubuntu has it's xorg assembled.
