Also: Even when calling gst_video_overlay_set_window_handle, vaapisink creates its own X11 display. Specifically gst_vaapi_create_display is called, and not gst_vaapi_create_display_from_handle. So even though we pass an X11window handle in, vaapisink will create its own X11 display.. not sure this works.
