There's a tool you can use to watch X packets. xmon I think. This
would let you see raw X error packets being sent - you can never
entirely trust programs to show you the actual errors.


Did you go with making a new window parented by the supplied window,
or drawing directly to the given window ?  Do you use the existing
colormap or try to impose one.


One thing you can try to simplify the world is to use Xvfb or
something to give yourself a limited X server. Eg if it only supports
one colour depth, or only static visuals, windows can only be of a
certain configuration.
