So, i was messing around making powerful weapons on Creative, and i made a Trident with Riptide and put a shield on my off-hand. But, whenever i launch my self into the sky with the shield in the off-hand, it gives this really weird effect.

(BTW, YOU CAN ALSO TRIGGER THE EFFECT BY USING THE TRIDENT ON THE OFFHAND AND THE SHIELD ON THE MAIN ONE, WHEN LAUNCHING YOURSELF IN THE AIR)
