Comment 2 for bug 776204

After some time of using Cairo-dock after the upgrade from 10.10 to 11.04 I have issues that freeze my screen.
I have had several times a complete hang of my PC.
In some cases I could ctrl+alt+f1 to get to a terminal.
Top showed compiz running at 100% cpu.
It seems to be a cairo/compiz issue.
Perhaps this is related to the changes for Unity in Ubuntu?

I experienced this in both the classic login and the unity login.

Similar issues are described here:

I am not sure what else to rapport, I have been unable to make a decent apport.
Please post if you need more info
