When using a trident with the Riptide enchantment underwater, if you are using a shield in your off hand with the trident in the main hand, as the riptide shoots you forward, the shield seems to clip into the face and block the camera. I tested this only on Java and do not know if it affects other versions. I only had Riptide I, so it might happen with more powerful enchantments. This is on a survival world, version 1.16. Thanks.
