noise in render

Hi folks,
First patch / First post!
I am experimenting with text through a geo comp using a delay to create feedback.
No matter what I try I can’t get my final render clean, I can see bands of lines horizontal and vertical in the graphic / most likely due to the instance repeating itself ? - Is there something I can add to improve on this?

Maybe try adding a tz channel to offset your polygon instances slightly so they are not all rendering at z = 0.
