Public bug reported:

Binary package hint: xserver-xorg-video-ati

After upgrade from karmic I get 2x higher Fps in glxgears(about 1700
FPS), because KMS is enabled by default.(In karmic KMS did not work).
But gnome desktop environment (with or without compiz) is about 3x
slower(gtk-perf) against the same desktop environment with KMS disabled.
Also I get 80 FPS with compiz-benchmark, when KMS is disabled, but when
KMS is enabled, I get hardly 30 FPS. Also mouse cursor appears after
start-up, when KMS is disabled( please see
https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-
ati/+bug/528115). However, when I disable KMS, I get 800 FPS in glxgears
and opengl windows do not behave correctly(like in previous versions of
ubuntu:karmic, jaunty...-see screenshot attachment).

Thanks, Majo
