enabling mixin.fastmath.joml creates small gaps in some blocks

[VindSole]

I have been trying to get rid of this bug, narrowing it to this setting on this mod, basically it creates very small gaps on some block's corners, allowing to see the sky and caves behind like an x-ray, only seen this bug happen on gravel. Odd thing is not all affected blocks show this behavior, to see it go into a dark cave and look for, or place some gravel.

mixin.fastmath.joml = false

mixin.fastmath.joml = true (zoom into the gravel)

Do you have other mods besides Potatoptimize installed?

I’m not entirely surprised about this sort of behavior. Fast math does sacrifice precision for performance. This looks like it could be some precision issues. I’m not entirely sure if this is something fixable. I’ll see if I can reproduce this issue on my end to determine if it should or shouldn’t be fixed. Thank you for reporting this!

Only this mod, if you believe this is not fixable I suggest adding a few words about the issue on the readme. Thank you.

If I can figure out exactly which Mixin is causing this issue, then I can separate it into the "unstable" category. That way we get the most performance optimizations without sacrificing visual quality
