Question Weird purple artifacts on GTAs grass

whatever, still a "shot" of the screen.

and have you tried completely reinstalling the game?

also try as @kerberos_20 suggested.

Literally on any short grass

I drove around a bit, i saw some pink flowers every now and then but not pink grass. If you say it's everywhere i guess the game's graphics isn't being processed properly. Hdmi cable wouldn't cause that nor psu, this is totally game or graphics driver, cache etc. @kerberos_20 suggestion should fix it.
