Affects Version/s: Minecraft 1.8
Fix Version/s: None
Not sure if it affects other versions.
When a player is shifted (crouched) in front of another player, so that their name is see-through, you can see through the other player where the letters are (weird to describe, look at the picture).
When looking at the picture, notice how the letter's in supermage113's name are showing the blocks behind willandkirby's head (through his head).
Again, this is kind of weird to describe.
