I have tested this on 64bit KDE 4.2.2 with kwin compositing and Mathematica 
7.0.1 on two different machines, one using the proprietary Nvidia drivers, 
the other the Intel graphics drivers. In either case, 3D graphs worked 
without actively manipulating them.

Therefore this might be an issue with you ATI drivers. I have no idea 
whether this will help, but you might try different drivers, e.g. the 
proprietary ATI driver (Catalyst 9.4 for Linux has been released recently, 
IIRC).
