Optifine?:
If so what version:
Does adding/removing Optifine affect the issue?:

Having this issue, v5.6.4
I'm using Optifine HD U E3
Removing Optifine does fix it, but I'd like it to work with optifine still

Optifine is a pain to get to work, mostly due to its private codebase, and the fact that it is constantly changing. The current version works with some version of optifine, although i forget which. I am planning on a rewrite that should hopfully fix all this

I'm experiencing the same issue with incompatibility between Secret Rooms and OptiFine 1.12.2 HD U E3. I know that this issue is months old, but I would REALLY appreciate a fix for this version of optifine...Since I'm really stuck with forge version 14.23.5.2838....and only this version of optifine will run on it. I'd be willing to donate if it would help / encourage you to give it a try. =)
