The unity8 shell session will not take advantage of this background opacity. It will always just fill the screen with its dash. I assume if the background is filled with a surface, there isn't a performance overhead?

The greeter won't use any clever blending or blurring effects for the first go, just have some 0-opacity parts of the screen. Later on, we want to add some blurring, but that would of course go away after you log in.
