Under the chameleons. there appears to be a void under them, it's on and off and I DO have Optifine. I just wanted to let you know.

I will be closing this issue because the source of the problem was found and there is no way to resolve it to my knowledge. I can reopen if anything new happens.

What is your version of Cold Sweat/Minecraft/Optifine? I can't seem to recreate this issue

Forge 1.20.1, Cold Sweat 1.20.1 v2.2.3, Optifine HD U I6

I got the problem to happen only when "Fast Graphics" was turned on. I wasn't able to verify why this occurs, but Optifine does warn that their custom renderer might conflict with mods in certain scenarios when using this setting.
