Just a guess, but this sounds a bit as if one buffer (either front or 
back) is never written and displays it's original content every other 
frame. Any chance you perhaps have two buffer swaps in your code [1]?

        Cheers,
                Carsten

[1] IIRC GLUTWindow already does a glXSwapBuffers() call, so if you have 
a glutSwapBuffers() at the end of your display function you'd swap twice.
