If a texture pack has some upscaled textures, the enchantment glint is applied to the entire 32x32 area even on weapons that are only 17x17. This causes nearby items in your invetory to have some parts that have the glint too when they shouldn't.

Its crearly visible that with this custom crossobow texture, the glint is also applied to a part of the enderpearl and the steak.

A possible fix would be to have the glint not apply on fully transperent areas
