XPS 15 9560 Flickering Line

Good afternoon, I bought a DELL XPS 15 9560 about 2 weeks ago, and 3 days ago I've started noticing a strange flickering line in the middle of my screen. Sometimes the flickering is in the entire screen (but not common), however the line is ALWAYS here.
I use my laptop for multimedia work, 3D and so on. Until now it never overheated or had any harm done by me.
The screen is a 4K touch display, but I never use it as touch.

Recorded 2 videos with my phone, since when I tried using Bandicam to record my screen it didn't show up.
