I have the solution for Intel UHD630 sudden artifacts. Change the SMBIOS from iMac18.3 to iMac14,2.
I have ROG STRIX Z370-I GAMING and i5-8400 and i had the same problem.
My build using i5-8400 and Z370 pro4 mainboard, I Updated from High Sierra 10.13 to 10.13.2. Everything work well but after wake up from sleep Chrome can not load any website and Safari can not play video on YouTube. Anyone know solution?
