You mean, it will not affect the following FOR_EACH_FRAME loop? If
so, I don't think I follow.

I don't think windows are the problem: Emacs knows very well which
window(s) actually need(s) to be redisplayed and redrawn. The problem
is with frame decorations that don't belong to any window: there we
rely on the OS and the WM to refrain from redrawing stuff unless
really needed.
