I don't know the detailed semantics of your window system, but this is
usually a sign that your application catches the mouse events such that VLC
cannot get them. You need to fix that.

I don't think this will work. The "mouse-moved" coordinates must be
expressed in the original video resolution, while the caller only knows the
mouse coordinates in the screen and/or in the window.
