Thank you so much Clement, this was all I wanted! I wish you the best of luck with the project, I know nothing about program development but an eevee rewrite sounds like a lot of work. Also sorry Thomas for all the trouble, just wanted to thank Clement :D

I've tried this, doesnt seem to be anything to do with screen space refractions, volumes or anything like that, they appear as samples progress. This doesnt happen to me in Blender 2.92 but happens in 2.93. I really hope this will be an EZ fix, because 2.93 got some amazing eevee updates i need to get my hands on.
