I have this problem as well. It appears to be related to sounds loading. It seems to only be certain sounds (cow, minecart, ladder, a few step sounds, and especially a certain ambient sound that plays occasionally), but the game freezes for a couple seconds right before/while playing them. Pressing escape to pause the game and then unpausing it immediately fixes the lag (and causes the sound to stop).
