Thanks for the forensics. They clarify things with Bug#48268.

Can you tell me why we do not SET_FRAME_VISIBLE when receiving the
MapNotify event here? Probably because we are not yet visible - though
mapped but invisible is a queer state.

Maybe we should process VisibilityNotify events.

Relying on these for setting visibility will fail for anyone who doesn't
send us an Expose event.

So here we don't get a MapNotify anyway when switching back and using
VisibilityNotify should be TRT.
