They need to be ordered by sub-surface relationships, i.e. what is the parent surface for a sub-surface. Z-order is completely irrelevant here. Also wl_surface creation order is irrelevant. What is relevant is what you set as the parent wl_surface in wl_subcompositor.get_subsurface request. You can create a sub-surface tree in any order by creating the wl_subsurface objects in any order. The relevant thing is the final parent surface <-> sub-surface association graph (actually a tree) when you start doing updates (commits) to the wl_surfaces. Thanks, pq
