This is by design. It's a trade off between all the the ugly paint and window frame problems we we had before vs. briefly hiding the window while we transition.

> the the ugly paint and window frame problems

I do not believe.
I have never experienced the  ugly paint and window frame problems.
And the flicker is worse than before, I think.
And Bug 646374 happens due to regression of Bug634586.

Since this was an intentional change, won't track for 5.  Discussion can carry on with UI team if necessary for m-c.
