Its because of double tap to wake is turned on. You have to turn it off restart the phone,and check that it stays off after the restart. Try that I had the same problem. After that everything is smooth for me.
I had this before amber update =p, I guess it's related to quantity of apps and the fraction of second between your touch and the screen, many users have reported this, and there are some that say when they hard reseted it, was running perfectly smooth, then when they backed up everything from their microsoft accounts (apps, musics, etc) it happened again..
