Could you check if the following workaround works for you?
Type the following line in a Terminal
sudo apt-get install compizconfig-settings-manager
Start Advance Desktop Effects Settings (System->Preferences->Advance Desktop Effects Settings).
Click on "General Options" under "General", uncheck "Unredirect Fullscreen Windows" (should be 3rd from the bottom).
Click on Back and Close.
This seems to be related to bug #153204.
