Working with type in a noise top

Hi TD-community!

I’m playing around with making an iridescent look in Touchdesigner, but I’m having a bit of trouble when I add text into a noise top. Like my resolution is 1080 x 1080 on everything, but somehow the text seems kinda pixelated with a hard edge:

I’ve attached my network .toe here.

All ideas and suggestions are welcome.
