I've had a few missing textures black or white more often with the new rendering system
I had the red texture glitch too but that was a while ago before the patches
edit: i have attached a "bugit" report with a screenshot, the location in the map is irrelevant i think as it happens randomly on any map.
I've also noticed i get more texture flickering to white since I've set the new rendering system on and the game freezes more (frame rate drops).
As for my system it's a Dell XPS 15 9560:
