This bug also affects me. The fixes suggested by comment #8 here (https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/1072206/comments/8) worked perfectly to solve the problem. If you don't have the Compiz Settings Manager already installed, you can find it in the Ubuntu Software Center. Thanks stojic!
