Please see bugs marked duplicate of this one for additional info about hardware affected.
At least myself and one other that are experiencing this problem did NOT experience it with Compiz enabled in previous versions of Ubuntu.
Compiz is apparently enabled by default, so this is a showstopper for new users.
I can also confirm that this bug still exists in today's RC.
