Game stutters when breaking grass/dirt with diamond shovel

Im clearing terrain in front of my base and when i break the grass/dirt for a brief second the game lags and i can see that in place of the block that was just broken is some particles for the grass/dirt and that block space is black. Then the dark spot disappears and the game continues as normal. With further digging, the dark spot is not showing up again but the lag when digging dirt remains.
