<pre>I'm trying to use a HD7480D on a cpu A4-5300 APU but I get many artifacts on
the screen and I get poor performance (with glxgears using the fglrx driver I
get at least 7k fps with the radeon driver fps 1k).
I've tried using various kernels starting from 3.4.41 to 3.9 rc8, the radeon
driver 7.0 7.1 and git and mesa 9.1 and 9.2_20130404.
I also tried the following options:
Section "Device"
Identifier "Radeon"
Driver "radeon"
Option "EXAPixmaps" "off"
Option "AccelDFS" "off"
Option "SwapbuffersWait" "off"
Option "ColorTiling2D" "off"
Option "ColorTiling" "off"
EndSection
Plus I've done tests from various live distributions to be sure that nothing
is wrong on my system (getting the same artifacts).
Using nomodeset I get no artifacts on the screen but very low performance
(glxgear get about 4 fps).
