When ximagesink is given a new window handle, it should check its geometry and if the size of the new window differs from the previous one, create reconfigure event in order to get a chance to negotiate a more suitable image resolution with the upstream elements. We can't rely on receiving Expose or ConfigureNotify from the X server for the newly assigned window, which would also generate reconfigure. https://bugzilla.gnome.org/show_bug.cgi?id=765424
