Title:
bad flickering with Radeon drivers in 12.04 Precise
Status in “xserver-xorg-video-ati” package in Ubuntu:
Fix Released
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.
