computer freezes when pressing "windows button+ atl+right mouse button"

Binary package hint: gnome-compiz-manager

I'm using 7.10 beta and I installed GL Desktop so I could configure Compiz-fusion. And on the Annotate plugin I had to press <super><alt>Button3 to erase what I've drawn. And when press it my computer freezes up. The mouse will still move but pressing stuff won't do anything. And I could still press <super><alt>k to erase all of what I've drawn (And it worked.) but It was still froze. I had to press and hold the power button to shutdown. This happens if I have the Annotate feature enabled or not so I don't think it has to do with that. But that's how I found it so it could have something to do with it.

And if I put in the code

lspci -nn
