Thanks for testing.  Maybe Bill could compare his setup with yours,
and that could give a clue.

I will try to study the code involved to see if I see some difference
between a complete redraw (which evidently doesn't have this problem)
and partial redraw (which does).  But I'm not familiar with the
display-specific code of the Windows port, so chances that I will find
something by staring at the code are slim at best.
