XPS 9560 Screen Flickering (not like the old xps15 problem)

Hi all

Appreciate any help here. I got my xps 15 (i7, 16gb, 1tb, 4k) as soon as it came out and overall have been very happy with it. Coming from a long history with mac book pros there have been a few adjustments to be made, but overall it's a great computer. Until yesterday, I have had no problems. Now though, I have this weird intermittent flickering of the entire screen. I am familiar with windows in desktop form, so the best way i can describe it is as if the GPU is being overclocked beyond its thermal limits and is starting to show artifacts. It only lasts for a split second, but usually occurs 2-5 times in quick succession, then goes away. This is during normal web browsing, nothing intense. Gonna run Valley benchmark now to see if that induces it.

Any ideas?
