This looks more like a driver bug. Btw, why are you connecting to your monitor with HDMI? For computer monitors, you use the DVI port, not HDMI. HDMI is for TVs. Unless of course your monitor lacks a digital DVI port (DVI-I or DVI-D). If it only has a DVI-A port, only then is HDMI the better solution.
