Are you using Optifine or any other form of mod that modifies graphics? Shaders, FoamFix, Vanilla Fix, etc?

Can you verify if this occurs without Optifine being installed?

Sorry for bothering you!

Can you verify if this occurs without Optifine being installed?

Yes.
All of mods installed are listed in this picture, those mods which may modify game rendering are renamed into .dis files. I believe by doing this, those files will not be recognized as mods by Forge.

Okay, thanks! I just wanted clarification for that, I'll start digging into it further now and see if I can reproduce it without any other mods installed.

Unfortunately, I'm not able to replicate this in my dev environment.

This means that, most likely, another mod is responsible for this. Perhaps there is a tile entity renderer in view or an entity renderer in view that is corrupting the OpenGL state, hence why it only happens some of the time.

Example:

Have you ever tried to look at the icon from the other side?
This issue exactly is: the icon will be shown normally from one side, but turn into a black square when being looked at from another side.
If you did have tried to look at the icon from both sides and found nothing, just ignore this comment.

I was actually finally able to replicate this: it has something to do with the method of selecting the baked model and it being in close proximity to BlockPos.ORIGIN (i.e., 0, 0, 0). I've changed the render system to automatically pick the baked model and this works.

Just need to tweak the alpha.
