For the decorators try putting this in your Screen section in xorg.conf: Option "AddARGBGLXVisuals" "true"
For the missing windows this happens when you run out of texture memory (driver bug) or when you start compiz with a minimized window (compiz bug). The cube thing is a separate bug, already filed. As for the speed, compiz screams on my GeForce Go 7400. With all that in mind, I believe this is a configuration error and not a bug. ** Changed in: compiz (Ubuntu) Status: Needs Info => Rejected -- compiz does not show window boards or the cube https://launchpad.net/bugs/80778 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
