Maybe can you just try to reproduce this bug after having disabled Xinerama support from FGLRX/Catalyst control panel?
> Though Xinerama does not support 3D acceleration i need to use gnome-fallback-mode.
I'm not using more than one monitor but when I did it a few weeks ago, I was able to use a Cairo-Dock session with Compiz and 3D acceleration.
Or is it maybe just a problem with your ATI drivers?
