I'm not tracking this discussion, so apologies if what I say below
makes no sense. However, the Emacs display engine avoids redrawing
anything if it concludes that what's on the glass is correct. So just
calling 'redisplay', or making some simple changes that don't require
significant redrawing, don't necessarily result in calls to low-level
drawing functions, you need to do something drastic to force those
with 100% certainty.
