I've determined what "instigates" this, but I find that it only mainly
affects mintty and somewhat affects emacs. I've never seen a symptom
in any other application.

I use a tool called "Windows Caffeine" that is used to keep the
display awake.  It sends a "f15 key up" event every 59 seconds.  That
is what is producing the "~" character in the mintty window.  I've
also seen a symptom from this in Emacs, but it's harder to produce.
It's not as simple as just having a text buffer in focus. I haven't
been able to reliably produce it in Emacs, but the mintty symptom is
very reproducible.
