Steps to reproduce:
Make a gap which is 0.5 block wide. You can use the combination of a full block and a stair facing towards the full block.
Play a little longer (> 1 hr).
Walk towards the gap while making sure that your sight is parallel with that gap.
You’ll probably fall into that gap where you normally won’t, meaning your hitbox is distorted (player’s width <= 0.5 block wide).
According to Wiki, a player’s hitbox should be 1.8*0.6*0.6 block.
