i used a gl.asyncread to getback opengl matrice and apply "effect" (feedback) whose go on a gl.videoplane.
with when i do fullscreen on my second computer screen i have piksel bug and rendering failure. it doesn't make it (bug piksel) when i make fullscreen on my screen computer (mac).
then the asyncread doesn't refresh. (picture)
i have also try to used different layer. boid drawing on layer 1 and videoplane on 2, asyncread read layer 1. but nothing good.
is there problem because i loop the opengl rendering ( read on asyncread and send back on a gl.videoplane whose read again by asyncread…
Asyncread also have the same name as jit.window and

if you can clear me about where come from the asyncread data ! is it read before him or not ?
and if you have a suggest about why i have problem with fullscreen on second computer screen and no on screen computer!

maybe, it's better if i used gl.node ? can it do my request ?

can’t really test your patch without the missing externals and poly~ object, but i can tell you that the @layer attribute should be some hight number like 1000. you want the asyncread to draw last, so that all the other gl objects that you are capturing have already drawn.
