Skyrim: Purple/Black/Changing Textures - HELP!

[hazymorning]

I'm having an issue with certain ground textures showing up as black at one angle, then when I shift the camera it changes to a different texture depending on the angle. I noticed this issue in Riverwood and areas where crops are grown (cabbages, potatoes, etc).

Also, the dirt where the crops are is always a purple texture.

I have verified the integrity of game files, and all of my mods are clean (no ITMs/deleted references) except a grass mod, SFO - Expanded Diversity. Even when I cleaned that mod + master files it made no difference with the texture bug.

I have a brand new PC I built just about a week ago, here are the specs:
OS: Windows 10 64-bit
Motherboard: STRIX Z270E GAMING
CPU: Intel i7 7700K
GPU: NVIDIA Geforce GTX 1080 Ti 11GB
RAM: Corsair 16GB DDR4
HHD: 2705.56 GB free

edit - I disabled my grass mods and that got rid of the black textures on the ground, but I still haven't found out what is causing the purple textures.

I know I'm late but just in case this is still a problem,

If vanilla skyrim has the problems:
Reinstall the game, start new game, check if the bug/glitch is still there.

If vanilla skyrim doesn't have the problems:
Try unloading mods that effect the types of textures that are weird, if that doesn't work try unloading them in let's say 5 at a time, and keep narrowing it down to the mod that causes it.
