Created attachment 141835 Glitch. Team, I picked up a new Lenovo IdeaPad 720S which comes with the KabyLake i7-8550U chip with Intel 620UHD Chip. Ran the Intel SSU Scan Tool and sent to their support and Intel told me to look here for the driver but I can't find it. Basically my screen is flashing like crazy and I'm hoping to find the driver here. Also running Ubuntu 18.04 LTS, 18.10, Arch, Deeping, CentOS 7, and Fedora 28 all have the same glitch. Also attached is a 10 sec video of glitch and below is dmesg output.
