    I also get this issue. 3000-4000 yellows within 10 seconds of moving the camera in the editor or ingame. Unity seriously needs to stop screwing up their own engine with every other 5.x update. :/

    This needs to at least tell you WHICH sprites are problematic. I see many people upgrading to 5.6 are seeing this.
