This phenomenon can happen if the game is overly saturated somehow, I can't explain better but I've experienced this before and it's very unpleasing to look at since the black and white keep flashing in the screen.
This happened to Joshimuz, a GTA:SA speedrunner, although I can't remember which 2hr+ stream he did nor how it was executed. I've seen too many now that I come to realization...
You've officially broke the game!
