Black lumps across player 2's screen when another player is in a minecart, boat, etc

How to reproduce bug: just simply have 2 players in the game and have player one go in a minecart or boat etc.
And you should see on player 2's screen black blobs or blocks or black screen
Oh and just keep in mind this is in splitscreen
