Public bug reported:

Binary package hint: compiz-core

It happens when I turn Window Management/Grid on/off through compiz-
decorator. It's reproducible.

I'm not sure that the bug is same as
https://bugs.launchpad.net/ubuntu/+source/unity/+bug/742326 and
https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/750008 .
