Yes, this must be a driver issue, because I checked it today with a laptop which has an Intel GMA X4500 and there was no stuttering. In fact this makes the open source driver useless, because under Unity 2D theres no stuttering, but I got video tearing instead on both machines (bug 792315) and the ATI X200M is not supported by the proprietary driver (Catalyst), so I'm unable to watch videos properly on 12.04.
