Major performance problems on SuSE 10.1 Beta1 x86-64

Hello,

I’ve installed SuSE 10.1 Beta1 x86-64 and encountered an extremely
degraded performance for all SDL based applications there. Drawing the
application window is so slow that one can watch it being drawn from
top to bottom, which happens both the initial window creation and
screen-wide SDL_UpdateRects operations.

I’ve then compiled SDL 1.2.9 myself, but that didn’t change anything.
Even with testalpha one can see how the background shading is drawn,
which takes perhaps 0.1 - 0.2 seconds - instead of being there
instantaneously.

Have others experienced the same problem? SuSE 10.1 Beta1 is using
X.Org 6.9.0 and I’m running the supplied radeon-driver on an ATI RV350
(Radeon 9600).
This doesn’t occur on my Debian system, which also uses X.Org 6.9.0
with Radeon-driver on x86-64, so it’s somehow SuSE related.

Any ideas how to solve this problem?

Regards,
Martin

As a follow up:
The maximum speed for SDL_UpdateRect was 2 fps

The problem was
Option “Composite” "On"
in xorg.conf

Turning it off solved the problems.

System: x86-64, X.org 6.9.0, radeon driver, SDL 1.2.9
