Rust graphical glitch

So bought rust today and played it for the first time. When i started to walk my grass was there, then it seemed to flash when i walked, it looked like it stood up then went back to normal, or as though my grass was missing or something. How would i fix this, is it with my drivers?

This is unheard of, you might want to contact garry directly via mail. This is very serious [I don’t think anyone has ever encountered this before]( flicker).
