Hi,

Thanks for your answer, Berk.

I just tried to do it this way (started two X servers and arranged for 
each window to have its own), but (still using the mandelbrot source) I 
just got black renderer windows. When I interact with the scene, it 
appears, but as soon as I release it an it gets fully rendered the 
display area goes black...

This would be very helpful. Thanks.
