When I start the game there is constant flashing horizontal bands across the screen and the coloration is green or pink. It reminds me of when you have a monitor that is not plugged in all of the way and so the color is wrong. I checked that it was plugged in all of the way though. If I put the game in windowed mode the problem goes away. The problem does not show up in screenshots. Other games look fine. This only started happening in the last few weeks.
