Anyone else having issues with flickering grass an rocks? I've cut everything in settings off an on to try an figure out what's causing it, but still having the issue. weird bit is if I pan the camera down an stare at my feet an run backwards it goes away for several minutes then starts up again. not sure what's causing it. can anyone help please?
