enchantment glint visual bug

the enchantment glint in 3rd person view can look differently from different angles. it is either normal, slightly red, or completely absent. only armor pieces are affected, sword did not show such behaviour.

How to replicate - In creative, enchant the armour (in the example, netherite is enchanted with maximum legal enchantments, although further test with diamond armor with 1 enchantment also suffers from the bug, exact shown in screenshots), and then in 3rd person the glint will look differently depending on angle, coordinates, or both. different chunks seem to have no effect, as the glint can switch even in the same chunk with the same angle but with a different position. different armours are affected (netherite and diamond were tested)

FOV is set to 100, testing on diferent vaslues did not seem to have any effect
