I mean that this change can cause unnecessary updates of all windows even if there is no such necessity. I do not how to evaluate this. So if somebody knows, lets check.

I agree with Ivan. We must be sure that unnecessary window updates are avoided.
This could lead to CPU overhead or to screen flickering.
This needs a careful investigation before making such a change.

As a side comment I would add that when a view is first opened it is drawn twice (2) which, to me, is a bug.
