Public bug reported:
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.
