Maybe I'm just dumb today, but it seems the result returned by
XGetWindowAttributes() is not deterministic.
XConfigureWindow (d, w, CWX, &wc);
XGetWindowAttributes (d, w, &wa);
Some window managers, uwm included, cause the server to redirect certain
requests. As a result, the request is not executed immediately, but
turns into an event to the window manager, who then (eventually) acts on
it. The ConfigureWindow request is being redirected by uwm, and uwm may
or may not have a chance to receive and re-execute the request before
your client's GetWindowAttributes request is executed.oj@apollo.uucp (Ellis Oliver Jones) (06/02/88)

One thing to add to RWS's reply: Some window managers (uwm not included) reparent the client's top-level window. Thus, when you look at the x and y members of the XWindowAtttributes structure as filled in by XGetWindowAttributes, you may not find values relative to the root window. /oj
