Night light and constant flickering on one display
 

I have a dual screen setup over DisplayLink. It has two very annoying problems:

1.) Standard Windows feature called "Night light" only works on Display1. Display2 always remains in day mode.

2.) Also Display1: it flickers a lot, especially after turning back on from sleep mode.

I tried to change the cable, and it seems the problem is specific to one port of the docker.

When screen flickers Windows detects a detach event, just like if I would detach the cable from the docking station.

Pretty strange this is the second docking station doing this, and I have tried with 2 different PCs.

DisplayLink driver is the latest (10.2.6841.0). What would worth trying (beyond completely leaving DisplayLink over Thunderbolt)?

I've also got the night light issue - HDMI works but not via DisplayPort on a D6000
