Massive holes on dh lods

I am using Distant horizons + reterraforged and whenever I load DH lods there are massive holes that wont generate that appear in a somewhat circular pattern. I have tried for months to identify what mod if any is causing this but if I add ANY performance mod to the modpack it causes these holes in the lods. This happens on forge and fabric and i have tried updating DH, downgrading DH, removing all the mods and adding them back, removing all terrain gen mods (it happens on all the ones i tried) and nothing has fixed it. Is there anything I can do to fix this??? A setting? A bug that could be causing this? A config that could fix this?? this is on 1.20.1 forge and fabric (I'm just trying forge at this point), tried 250, 512 and 1k DH render distance, different performance and quality settings, nothing has fixed it yet the mod list is the most recent one i tried on forge 1.20.1 lmk if anyone knows anything about this or knows what could cause this
