I don't know what "toy scenario" are you refering to, but certainly
emacs -Q
M-: (make-frame '((visibility))) <RET>
is not a toy scenario *at all*. For one, it will prevent
frameset-restore to restore invisible frames (I could work around it,
but it'll be a hack).

I think bug#14841 is a clue that the visibility mismatch between Emacs
and the Windows wm predates your pixelwise changes.

I would certainly prefer that you reverted your last change. You're
fixing an occasional problem and introducing a perfectly repeatable
one.
