Thanks for the bug report. I've changed the title because it was polemical and it didn't explain the problem. Please run the following commands in a terminal and attach all the files created (lsb_release.txt and lspci.txt).
Besides attach files .xsession-errors (in your home directory) and /var/log/Xorg.0.log
Also try to see if the bug happens with the default settings. To get the default settings, install "compiz-config-manager", launch it and then go to "Preferences" (left bottom corner) and click on the "Reset to defaults" button.
