Review of attachment 334911:
I don't think this is the correct solution. Before this patch you could set the
cursor and get rid of your cairo_surface_t reference without any unexpected
side effects, since the wl_surface implicitly had a reference to the cairo
surface via the buffer release callback. With this applied, would we destroy
the cairo surface would the wl_buffer also be destroyed (see
gdk_wayland_cairo_surface_destroy()).
You write that the issue is a refcount underrun, did you investigate how the
ref count went wrong?
For reference, each time one wl_surface.attach(buffer); wl_surface.commit(), we
should receive one wl_buffer.release on the attached buffer. Do we
cairo_surface_reference() for each time we attach and commit?
