Yes it helps a lot.
There are colored lines appearing in background, setting the looped gemframebuffer perspec fixes it, I will try now to found out how to turn background's black pixels to transparent.

Hello,
I'm trying to find out how to get a backbuffer for attached shader found in the web ( http://glsl.heroku.com/e#8849.0 ), it seem I couldn't get alpha channel in gemframebuffer's recursion, any idea?
I just added a line at the begining and an other one at the end of fractalFeedback.frag to change the alpha for the feedback. I also change the texunit ID backbuffer to 0 in the patch. You can change alpha feedback with the number box i added in the patch. Hope it helps. ++
