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,
