When I run the shaders with Distant Horizons in Fabric using Iris. I get a weird fog like wall at the vanilla render distance edge.
Minecraft version 1.21.8.

I have tried turning off fog, all fog in game goes away but problem stays.
I found Transparency setting in DH, did nothing or even made it worse when disabled.
It seems more like the usual render edge wall semi transparency didn't go away.
Is there a way to solve this?
