I had the previous workspace flash, and windows not moving to adjacent workspace problem when rotating the desktop cube.

Yesterday I tried Daniel vav Vugt's ppa:vanvugt/compiz-preproposed version, but had some different problems.

The cube was mostly fixed it seems, but most windows went plain white. Focussing or defocussing a window usually caused it to toggle between white-washed and correct, but some windows stayed white-washed, and I think some stayed correct. I'm using gnome-classic on 12.04, and after I logged in again the panel was white-washed too (its content was functional but hidden). Also, when I tried the expo, the textures for the desktop were a bit mosaic (too small and repeated, or displaced and so on). I couldn't analyse it much because something started to chug and the system soon hung.

I'm using a lenovo T420s with following graphics (couldn't get it working in Optimus mode, so chose Integrated graphics in the BIOS). Also tried compiz with and without the nvidia driver enabled, but it didn't seem to make any difference.

Good luck getting on top of this Daniel. My guess is that some texture parameters are getting set incorrectly, and causing white-wash if one is lucky, or a more serious corruption if not (I guess the expo requires more/larger textures and is hence more likely to propagate corruption).
