When playing call of duty warzone my screen goes all rainbow with pixels everywhere and I can't see what I'm doing. But if I turn in a different direction it goes away. It happens a lot at farmland and also at the frozen pond. And now it's doing a lot more all over the map.I know it's not my graphics card because it doesn't do it with any other games and I know it's not my monitor because of the same reason. What can fixes and what could be causing it?
