Seems to work fine for me.  I see the "normal" flickering, no slow-paint
rectangle.

Same here.

Doesn't make a difference, I still see the slow-paint rectangle.

=======================

At any rate, if I've understood the responses from Eli, it sounds like
there isn't any bug here, just that we haven't implemented double
buffering for Windows.
