Yes.

The GUI's video window flickering was due to the window manager drawing a
background as soon as the size has changed. MPlayer itself (xv video output)
doesn't do so, and with the patch to come the GUI won't do either.

It's not a scaling issue in my case, but maybe I can learn something from
your patch.
