When ignoring an update, request one for later

Browse Source 
If we were not ready to paint the screen, this does not mean that we
should give up on repainting, just potpone it.

I thought that it was bad to call update() in the paint event, but I
cannot find reference to this anymore and everything seems to work as
intended.

Fixes part of bug #11323.
