Note that GstVideoOverlay is just a stupid interface without any actual logic
;)

Some more observations here: xvimagesink and ximagesink fail this way. But
glimagesink and eglglessink don't. Although they require the exact same XID and
just do the rendering differently. So the problem here is maybe that
ximagesink/xvimagesink need some different code path for RGBA visuals than for
RGB visuals.
