Thank you for your answer:
well it is still not working but i realize that the error is in fact coming from the canvas.beginDraw() and canvas.endDraw() instructions.
If i comment out all the stuff related to Syphon it is still the same error.
I know that now it is clear that it is linked to Processing (alpha 5) and not to Syphon. So i am sorry that i posted on this forum.
But if you have an idea it would be so cool if you tell it to me anyway.
I did reproduce the problem inside the Processing editor with sendFrames.pde example from Syphon after having commented out everything concerning Syphon in it.
thanks a lot for your time
