I had the same problem. Now, after upgrade to Gen 2, scrolling within apps is much smoother, but in system things, like settings, contacts, its still a bit laggy.
People who i asked many times about this problem, said that on their phones this problem didn't appeared.
If someone have any working solution for this, please post it here. On EVERY CM7 version since n29, scrolling isnt as smooth as it should be (considering to RLS4 an 5 SS).
all graphical boosts are off, animations are minimalistic and my launcher is the most simple launcher ever- launcher pro.
