Z-Fighting on piglins and player legs

Z-Fighting is present on the legs of the entities who have different colors next to each other,. As I could see, this ocurrs, when no armor is worn, on piglins, his variants, and the player. This doesn't happens on zombies, for example, because both legs have a symmetric texture. Although the z-fighting it's stil ocurring, it doesn't show up because of what I mentioned.
