After Mavericks Update installation my MBP 13' i5 mid 2012 HD4000 is been presenting noticeable graphics lag when scrolling (Safari, Chrome, Dock, Scrolling sideways, Launch Pad, i can say everywhere).
It was working with no problems of this kind with Mountain Lion 10.8.5, everything runned smoothly.
Has anybody has or solve this issue ? is extremly annoying,
