The notes move faster after the update, because they need to pass a longer distance within the same time.I suppose you are talking about screen tearing. This is usually caused when the FPS of something is generally too high for your screen, have you tried using FPS limiters?
Of course I do have as much time to look at them as I used to, however my screen is really crappy, and any increase in speed causes the smearing to get worse (I'm not even sure if that's the correct word). I've had issues with some maps before the change because of that, but the wide screen support increased the number of those.
