I don't think so.

Ok, so #37 for video, #43 for GUI.

Where is the OSD rendered? Is it rendered on the GUI layer?

Video plane, rendered full screen above the base plane without alpha.

Here should be the GUI, but this plane is not active.

Could you post a state where you expect something else than is actually
seen?
