Block lag in Singleplayer

Ever since the update to 13w23b, I've encountered block lag. I had no block lag of any kind before on single or multiplayer.

When I logged out restarted my computer and logged back in was still there. But once I rode a horse far away from where the block lag was occurring (I thought that maybe all the horses near my house was causing it) the block lag was gone even after I returned home.
