panel contents disappears on external monitor

[Greg Grossmeier]

Binary package hint: unity

I have connected an external monitor (an HP Compaq LA2205wg) to my Lenovo x200s (intel GMA4500) and extended my desktop (not mirror).

The panel on the external monitor where my indicators and login/time stuff are is disappearing and it appears text is not being refreshed correctly. See attached screenshot.
