Using Xbox series X, and my favorite texture pack pure bd craft, I've noticed that string, apples, hoppers, and a few other items have oversized visual scaled size compared to the normal size making it look like you're not holding anything in first person. I've noticed this with mostly HD texture packs, Modern HD, Creator Pack, Mizuno craft, and a few others i own, not sure if this is on the texture pack creators' part or if its Minecraft
