Hi, same problem here. I am using clean install od Kubuntu 10.10 with latest updates. After boot, the compositing is temporarily disabled. I am able to resume the compositing from KDE Control Center a then everything is working fine. After some random time, when I use some KWin effect (Tab-switching , desktop switching, desktop grid, ...), KDE hangs and syslog become flooded by messages described in this bug.
