It's a well known problem, but none of the solutions I've found was able to successfully run compiz. I've also tried xeffects overlay, and now the portage masked release. I'm running: x11-apps/compiz-settings-0.07, x11-plugins/compiz-extra-0.3.6.0 and x11-wm/compiz-0.3.6 (version >=0.5 does not compile because of an already opened bug).
