Weird artifacts in Windows desktop apps

Wondered if anyone could help. I am experiencing some weird artifacts in Windows 10 desktop apps on my Razer Blade 2018 1070 Max-Q version. Mostly they appear on the second monitor, but sometimes on both - laptop and second monitor. If you take Skype as an example, then it would have vertical moving lines only visible on images, the remaining parts of the app are fine. All other types of applications, including games, etc, work perfectly fine. I tried to change monitor cables to DP, HDMI, USB-C - same result.Also updated Nvidia drivers to the most recent ones.
