  icomment: Sorry, this is correctly the Tk repo.  You are apparently on the Mac
            platform.

            The MAC code got completly changed and now has a different drawing
            strategy.  It now draws on a shadow page, instead directly on the
            screen.  The older interface got deprecated by Apple and there were
            always drawing issues, that regions were not updated.  To my
            knowledge, the new drawing is just a big step foreward.

            I suppose, the different timings you are seeing are due to that
            reform.
