Glint flickering on held items

When I hold enchanted items the sides of them flicker constantly especially when moving around. It’s very noticeable on the bow. I’ve tried adjusting the glint speeds and strength in the in game settings but it doesnt do anything. I tried reinstalling Minecraft but it didn’t work either. Not sure if there is a graphics setting I should change. I’m not using any mods or texture packs. Please help.
