Same problem here, wonder if it is to do with Chrome 😟
I haven't been able to swipe back and forth through Chrome pages for ever, and then I wont be able to slide left and right through the screens I have, no Mission Control gestures or Expose, I can only scroll.
All Track Pad pref are fine and ticked.
I keep getting uncompleted animations when downloading files etc too, the file will download and open, just the icon still shows the download animation but stuck.
Mission Control always shows a partly downloaded bar from within the icon too.
Shame the last OS was so very stable, hope they get this one smoothed out. If they are trying to intergrate IOS and OSX, then they need to make the gesture bug a priority.
