Same problem here. Exactly the same as OP described. It has been going on for months/years.
Lenovo T420s
Nvidia NVS 4200M graphics card
Ubuntu 16.04.1 LTS
Nvidia binary driver 378.13 from nvidia-378 (open source)

I only notice this when I connect my external monitor to the DislayPort. Connecting via VGA connector does not give this problem.
