Hi Craig, Could you provide a reproducible example?
You are describing default wayland behaviour, which is to only show the surface on screen when it has a buffer. One solution might be to show an initial background on the window. I don't discard the possibility of a bug, so the reproducible example would help. -- Thiago.
