Clear Line Lag?

I'm new to this game, and I played lockjaw before this so I won't know if there are any patches to this. There seems to be a little bit of lag or time interval in between the time when I clear my line and when I place my next piece. I normally mess up because of this in sprint time. I'm assuming there is some way to fix this or else other people wouldn't have been able to get 2x seconds.
