Here is a bugreport on launchpad (all system logs are attached there): https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/806548

Comment 1 Chris Wilson 2011-07-07 10:34:25 UTC 
Looks like the FBC issue. Can you please try a recent mainline kernel, e.g. 3.0-rc6?
Comment 2 Dmitry Groshev 2011-07-07 10:36:22 UTC 
I've installed latest kernel a few days ago (linux-image-3.0.0-999-generic_3.0.0-999.201107040905_amd64.deb). Should I install newer one?
Comment 3 Chris Wilson 2011-07-07 10:41:18 UTC 
What does "cat /sys/kernel/debug/dri/0/i915_fbc_status" report?
Comment 4 Dmitry Groshev 2011-07-07 10:45:21 UTC 
it shows "FBC disabled: disabled per module param (default off)", but I have followed an advice from here: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/806548/comments/2 and it helps. I can install latest kernel and/or xserver-xorg-video-intel if you wish.
Comment 5 Chris Wilson 2011-07-09 03:28:55 UTC 
There is very little point debugging these whilst unity is in such a state of disrepair. valgrind has a lot to say about their rendering code, and everything else.
