Comment 2 for bug 1031940

Another important comment:

I set the duration to 2 seconds, and now I know what causes the flicker. The fade effect is going reverse! So the window I selected comes up, then fades out (insted of in), and then comes up again and stays. Obviously it should fade in from full opaque state, and then stay.

(Isn't this bug somehow connected to the rotate cube flicker bug? The effect seems to be the same.)
