Forwarding this bug from a ubuntu reporter: https://bugs.edge.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/363174 * See also [Problem] Compiz works like a charm until the blur plugin is enabled. Enabling blur causes X to slow down drastically. Screen garbage is seen on minimize and restoring a window. "Good" behaviour is restored by disabling the blur plugin and restarting X. This is with UXA enabled. Tested: -intel 2:2.6.3-0ubuntu9 -intel 2:2.7.0-1ubuntu1~xup~1 compiz 1:0.8.2-0ubuntu8.1 [lspci] 00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller [8086:2a02] (rev 0c)

I started compiz, ran ccsm, checked "Blur windows", clicked "Blur windows" checked "Focus blur", dragged ccsm over my now-blurred gnome-terminals, minimized and un-minimized, switched to each of the other blur filters in turn, and did the same thing. CPU usage appeared to be fine. Can you reproduce with Mesa master or 7.5, or provide more detailed instructions on how to reproduce the problem?
What's mesa master? I tested this with the ubuntu packages listed above. Should I try this with newer packages? If yes, where are they available?

"mesa master" means upstream mesa git master branch. Can you try the latest Ubuntu 9.10 Alpha3 (shipping xf86-video-intel 2.8.0 and mesa 7.5)?

Any updates on this bug? I'm not able to reproduce it, so if I don't hear something soon I'm going to close the bug.
closing as lacking of response.
