Display artifacts on fresh install with GTX 1060

Just installed 18.04.1 LTS, updated, upgraded, added in the Nvidia repo, and using the 396 driver. With all of this done, I’m getting random black line artifacts coming across the screen if I’m on a bright screen on my main monitor.

I’m using a GTX 1060, with two monitors, one connected via DVI, the other connected via HDMI. The DVI monitor is fine, it’s also an older monitor, but haven’t had any artifacts or anything on it. It only happens on my main display.

I have Windows installed on the same system (gaming), and the problem isn’t there, so I’m assuming it has something to do with software/firmware. I’m not sure where I should progress at this point. Anyone have any ideas?
