with forge version 36.1.0 and 36.1.1 the entities and water and some leaves render through solid blocks, you can see the water underground and every mob behind blocks. i first found the issue with optifine(HD_U_G7) installed, but even after removing optifine the issue persisted.

you can reproduce the issue by simply playing
entity culling was version 2.0.6

I'm unable to reproduce this with forge 36.1.0 and entity culling 2.0.6

Can be reopened when it is reproducible with just Entity Culling (and less than 5 other mods) installed.
