When I was playing Firestarter after songbird hacks into the stadium and we start getting all red glitch effects and grain effects, the game auto saved.
Later when I had to reload the save, the grain and sharpness filters were stuck on the screen. So I reloaded the save file to before the songbird events occurred however it was still the same. I then tried loading a completely different save file that doesn't relate to Firestarter but have the same issue in all my save files.
