[Bug 781536] [NEW] When using external monitor upper part of screen is missing

 

Public bug reported:

Binary package hint: xserver-xorg-video-intel

When I enable only external monitor and switch off  LCD panel  upper
part of screen is not being drawn for application windows (see picture),
strange is that  Unity Search bar draws OK, only regular application
windows and desktop are not drawn.

I didn't have this issue with 10.04 and 10.10
