If I enable windows effects the glxgears framerate goes down to 20 fps, moving
windows etc. is a pain.
Doing "compiz --replace" works as expected: glxgears is at the expected 60 fps
(synchronized with monitor refresh rate), wobbling windows are a real fun.

Because compiz does not work well with KDE4 I have disabled windows effects.

from /var/log/Xorg.0.log:
(II) LoadModule: "radeon"
(II) Loading /usr/lib/xorg/modules/drivers/radeon_drv.so
(II) Module radeon: vendor="X.Org Foundation"
    compiled for, module version = 6.14.3
    Module class: X.Org Video Driver
    ABI class: X.Org Video Driver, version 11.0
Chipset: "ATI Radeon X1200" (ChipID = 0x791e)

from glxinfo:
GLX version: 1.4
OpenGL vendor string: X.Org R300 Project
OpenGL renderer string: Gallium 0.4 on ATI RS690
OpenGL version string: 2.1 Mesa 7.11
OpenGL shading language version string: 1.20

That's expected. This's an upstream bug which wont be fixed anymore.
