Bug Description

After some period of time and most probably consequently after unity --replace (due to a non responsive unity/compiz) my additional screen in the dual screen setup is mostly black if I use it at a resolution > 1152x864.
Mostly means that the top bar of unity is ok but the rest is black and if I move a window from the main screen to the additional screen then the windows is not drawn.

I found out that removing $HOME/.gconfd/saved_state after having logout, will allow to "reset" the situation.

What graphics drivers are you using? Also is it unity2d or 3d?

I think it's unity 3d as I don't have any unity 2D packets installed.
