I have a fresh install of Ubuntu 12.10. on an Nvidia-Optimus laptop. Activating 3D Windows in ccsm kills the rotate cube effect. I attached screenshot of a situation, not even the worst - which is a completely black screen. Desktop Cube and Rotate Cube work fine.
I know one can live without it, but it is only too easy to get used to the good. 3D Windows is a nice feature to look at application windows on top of each other, so it would be very good to get it work.
Could anybody help please?
