Ha, clever. I kind of wish I'd looked at this closer before.
The fullscreen-shell says that a client (should) use 'either the
present_surface or the present_surface_for_mode requests', but this
actually uses both. It ignores the present_surface_for_mode feedback
object, so if a mode switch fails, it relies on the normal
present_surface request having made fullscreen live. I don't really
see anything in the protocol text which suggests that this is
something which should work portably.
Maybe a better approach, whilst you're here, would be to not destroy
the result of present_surface_for_mode, and then fall back to
present_surface if the feedback object returns failed? Of course just
directly calling present_surface if we're not sprawling.
Sorry, I know this isn't your doing, but ...
