I don't have an answer to your question, but you might consider switching to offline rendering for the command-line mode so that you don't have to mess around with windows and such. You can use -[NSOpenGLContext setOffScreen:width:height:rowbytes:] to point it into your own pixel buffer, thus eliminating the need for glReadPixels completely. Who knows, it might even fix your problem too....
