Unfortunately kmssink doesn't recognize during negotiation that the
overlay plane can't scale. For upscaling this is 'handled' by just
falling back to a centered, unscaled plane. For downscaling this fails,
as the unscaled frame is too large to be displayed.

I suppose what kmssink could do is check the display resolution and
crop to that during show_frame if the first try failed?


Yes.
