I sometimes get Compiz to freeze when doing the following (I also reported it on https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/148073): 1) Open Firefox in fullscreen on one screen 2) Open Totem in fullscreen on the other screen The the UI is frozen and if I connect to the system with ssh, compiz.real is running at 100% cpu. I could connect from another machine and look around in gdb. I found an infinite loop in paint.c, function paintOutputRegion() The loop: /* detect occlusions */ for (w = (*walk.last) (screen); w; w = (*walk.prev) (w)) { ... } ... is never escaped. I didn't check if this was fixed in a newer release (I'm using the 0.7.2 version from Ubuntu Hardy). I can provide more information if needed.
This seems like an incorrect window walker interface usage to me, thus a plugin bug. Can you please disable the following plugins, each one at a time, and try if this improves the situation: - Animation - Cube - 3D
Can you check if this issue persists with the latest compiz fusion plugins-main?
No issues at all here in git master. Please reopen if problem persists.
