Syphon and ofGLProgrammableRenderer

Hi all!
I have some problem to see my output on Syphon when i use ofGLProgrammableRenderer. I use it because i need for the shader, but when i try to send my texture to a Syphon Client, i don’t see nothing… it’s like to see a not clean fbo.
Did somebody had the same problem?

Could this be due to the Syphon framework not yet supporting the Core GL profile? See #13.

Thanks pizthewiz, could be this.
