You're lucky. Every Ubuntu variant I've tried in the past few months (LTS or 17.04, every desktop flavour), rolling and regular OpenSUSE releases, Debian 9 stable, testing, unstable, Gentoo, Slackware 14.2 with a new kernel (stock kernel in 14.2 can't use the Intel drivers), every damn distro
has horrible tearing on the Intel 620 graphics that's in my kaby lake i7-7500u laptop or the Iris 5100 in the i5-4278u that's my home server/HTPC.
Except for Fedora 25, which is absolutely flawless on both. (And maybe 26 which is released today.)
If you've got a solution, I'm all ears.
