How to fix choppy scrolling on 10.9 Mavericks? I just upgraded my mid-2012 MacBook Air to 10.9. Now whenever I scroll down a page, the effect is very choppy. The scrolling seems to stop and start very quickly. Also, sometimes the left part of the page will scroll down but the right part of the page will stay put for a fraction of a second. The net effect is very flickery and distracting. 

Any ideas on how to fix this? Slighly different case, but this guy was able to solve a very similar problem (external monitor) by opening AutoCAD (what the heck?).

I also tried resetting the SMC as recommended here. Still no luck.
Try System Preferences -> Energy Saver -> Automatic graphics switching -> Off
