It depends on how they wrote their engine but a window with 0% opacity or
100% opacity is much easier to render than something in-between.
The reason it is harder to render a window with opacity >0 and <100 is
because you first have to render the background and then the window with
blending options which is typically more GPU intensive, especially when you
have a lot of windows.
IMO a "good" engine will look at a window's opacity setting and if it is 0 then
it should skip the rendering process altogether. Again, depends on what
approach they took.
