<pre>Hi,
I suppose this is the common mistake: *_add_listener() sets the same user_data
member as *_set_user_data(). It's not exactly underlined in the docs, but it is
there: <a href="https://wayland.freedesktop.org/docs/html/apb.html#Client-classwl__proxy">https://wayland.freedesktop.org/docs/html/apb.html#Client-classwl__proxy</a>
for wl_proxy_add_listener() and wl_proxy_set_user_data().
The compositor has nothing to do with this. If you call *_set_user_data(), you
will overwrite the value set by *_add_listener().</pre>
