Public bug reported:

Switching between focused and non-focused window works very slow. It
ends up with Unity being slower than it should be.

To reproduce:

1. Minimize or close EVERY window and open Dash - opens up instantly, animation is smooth.
2. Open a single window, move it "under" Dash and try to open Dash - animation is a lot slower and it's very choppy. User might think, that it's because window is drawn under the dash and it just eats up resources.
3. Unfocus the window - by clicking on the empty space of the desktop. Notice that with the window open, animation is still smooth!
4. Open as many windows as you want and unfocus them - by clicking on the desktop. Animation is still smooth - so it doesn't matter how many windows are open, it's just changing focus.

This happens because of Unity grabbing active focus from the window.
Switching focus works very slow, and because of that dash opens slowly.
This affects for example switching to fullscreen in VLC or Totem.

This is not related to my older graphic card - I can run Crysis 2
smoothly, but changing focus works bad. Tried drivers from nvidia-
current to nvidia-331 - works the same on every driver.
