[TTVD] Ensure syncing changes to overlay mode on first possible frame

During transition from texture to overlay, last step is to
wait until all texture-backed frames are properly rendered
and then switch to overlay mode. As now it's done on worker
thread, there is one frame delay in mode changing.

Result of this is that first frame not backed by texture
data is not displayed using hole, but still tries to use
non-existing texture. There is no resource for it, so
it's presented as black frame.

This CL fixes this behavior by allowing mode change to
overlay on first proper video frame.
