Black grain when exporting .gif

Question

Hello,

I've been making some simple motion graphics for a presentation, all was going fine until I've decided to move the position of a layer underneath. As I have done that the colored part of my file has gotten a black grain on it (only after exporting). I have not changed any export setting, but when exported as an mp4 the problem is gone. I've tried everything I could think of within my composition but the problem remains.

First export: https://giphy.com/gifs/26xBrCwtMncY2ylDG?status=200

Second export (after moving away the black part of the wave from underneath): https://giphy.com/gifs/26xBRI9aj7sdpS7h6?status=200

I cant see the grain in preview and the only layer under the green wave is the background which is white. This could be a simple mistake, but please let me know.

Thank you!

the GIF exporter in AME lacks many features (and unsupported for Mac users) and I haven't yet seen anyone use it professionally. I have seen professionals use Photoshop for exporting GIF files (Render the video from Ae, then drag to Photoshop). if you make a lot of GIF's, I heard this script is very nice: GifGun - aescripts + aeplugins - aescripts.com

for optimizing your GIFs I would recommend this article: https://design.tutsplus.com/tutorials/10-ways-to-optimize-an-animated-gif-file--psd-34649

Instead of exporting the Animated GIF through Media Encoder, I have exported it as H.264 and converted to a GIF afterwards in Photoshop.

This has fixed the problem but I have exported a few Animated GIFS trough Encoder before and this has never happened. Happy to fix the problem but I wish I could understand the root of it..
