Using Optifine with Opti-fabric mod breaks chest, shown on a picture below.

Same image, without usage of shaders

Note: Chest's upper half renders correctly when opening chests

I wouldn't expect EBE to work well with OptiFine shaders. If you'd like a quick shaders solution i'd suggest checking out Iris or their discord server. I notice that you're also using better grass and likely a few other optimizations, there are alternatives for these too. This may be quite a bit of work, but the nature of OptiFine isn't very mod friendly...

Thanks for the reply, just thought you might want to know :D
