When flying with an elytra the player hitbox gets changed but the view point still thinks the player is standing which makes it 1 block higher than it should be. It can be seen by flying against a wall where the block outline will be 1 block higher than it should. This also makes you break and place blocks in the wrong location than you are looking at which is really annoying when building.
