I have upgraded my Macbook Prod 13 Early 2011 with Mountain Lion. Now scrolling between pages in Launchpad & Scrolling between Desktops and on some websites in Safari is not smooth at all. There is a lag while scrolling.

My Macbook specs are i5 with 4 GB RAM. I have shown this issue in Apple genius bar appointment they said to wait for next OS upgrade. Could you please suggest is there anything i can do to resolve this issue. It is very annoying.

You are not alone. I have the same problem with a 15" MBP early 2011 with 16GB memory. It is very annoying to say the least. It wasn't this way with Lion. This problem along with significantly degraded battery life has me wanting to go back to Lion :eek:

I'll wait for the .1 release and if both of these issues aren't resolved I'm going back.

try setting any stacks on your dock to display as folders instead - fixed the lag for me. i'm on a 2.6ghz mid 2012 non retina 15 inch.
