Weird Artifacts

Hello, I am having these weird artifacts and I can’t figure out what they are . I figured they were VFA’s, but I can’t rid of them. I’ve checked and am sure the belt is riding nice on the idlers. It’s pla. Any ideas??

It also seems to be dependent on the print file sometimes?

I'm starting to wonder if having the teeth of the hybrid belts riding on a smooth pulley (bearings) might be doing this. I see it in some of my prints

Oh yeah you could be right. But where does it ride on the teeth?

The top front idler /adjuster. unless I'm dumb and have it backwards

My understanding is that it should be the smooth side of the belt on the idler
