As described in
http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-libs/html/gst-plugins-base-libs-gstxoverlay.html#desc

you need to set it in a message handler in order to set it at the right time.

This sounds indeed like the element creates the window itself instead
of using the one you want.
