This is what I mean:

I know this must be inherently a DH problem, since the same thing happened with BSL. Thing is, BSL has an option to change the DH overdraw render distance and I cranked it all the way to zero and set DH's actual overdraw prevention to 1.0, which fixed the problem. Perhaps you could add a similar option here? I am kinda RAM-limited, so I'd rather leave my render distance at 8 chunks max

1.3.8 now has hardcoded overdraw prevention. Implementing an option to change the overdraw won't be necessary.

Works perfectly as intended!
