Same:
Thinkpad T430u (intel graphics - modesetting)
Thinkpad Dock USB3.0 Basic (latest drivers)
Ubuntu 16.04.02 - 4.4.0-65-generic #86-Ubuntu

Mouse movement is smooth, but keyboard input lags (on external displaylink screen).

Strangest behaviour I see, when I let the e.g. chrome window overlap just some pixels into the laptop screen, the lag (while typing into the addressbar) is not there, or at least less. If I pull the window completely on the external (displaylink) screen, it lags like 1hz.
