Your application is setuid (and setgid), so what's probably happening is 
the X11 "Magic cookie" that sshd puts into .Xauthority (with the "xauth" 
command) does not match what your application sends (since the uid that 
the application is running under has no .Xauthority or one that doesn't 
match).

Try telling your application (or rather, its X libraries) where to find 
the .Xauthority file by running something like:

XAUTHORITY=/home/yourdir/.Xauthority /path/to/yourapp

     Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
