This is somewhat messy, but you could check for a NULL return to
gdk_window_at_pointer(), and then use XQueryTree() on the toplevel
window (the one that you used gdk_window_foreign_new() on) to find all
the children of that window, and call gdk_window_foreign_new() on those
as well. At least that way gdk will always be able to see them. There
might be a way to grab new X windows as they appear as well, but I'm
not sure about that without digging a bit deeper.
