Sooo, for some reason, since the most recent update a few weeks ago, every time I upload my layers into pngtuberplus, it gives me a white/black pixeled outline to some of my layers? Like weird artifacting.

Anyone come across this, or know how to fix it?
It never used to happen so not sure what to do. I don't wanna have to go back to the previous version, since there's some features I'd be sad to lose out on. (also for my commissioners. rip)
