Comment 2 for bug 1051913

Additional info :- When dash is open on monitor 1, observe the launcher on both monitors are desaturated. Now with dash open, Drag any application or file or document over the dash area and release the hold (icon/file goes back to its original place), dont close the dash.
Observe that, dash is open and both launchers on monitor 1 and monitor 2 now look saturated (normal looking) even though dash is open.

This behaviour is observed on dual monitor set up, when tried on 2 machines with ubuntu 12.10 quantal with ppa:unity-team/staging, only 1 of them produced the above result.
