With lots of try-and-error I noticed that sticking a cairo_surface_flush() into
_cairo_xcb_surface_mark_dirty() makes the problem go away, but
_cairo_xcb_surface_flush() doesn't help. In other words,
_cairo_surface_detach_snapshots() is needed. Meh?

Digging a little deeper, I found out that the _cairo_surface_attach_snapshot()
created in _cairo_xcb_surface_acquire_source_image() causes this problem. Dunno
where to go from here.
