If you don't want the gaps, you have to set `frame-resize-pixelwise' to
true. That's what all other graphical programs on Windows do and that's
what I do. And that also means that dragging the border of an Emacs
frame will resize it pixelwise like the window of any other graphical
application.

It is fixed by setting `frame-resize-pixelwise' to t. So "wontfix"
won't apply ;-)
