I'm having an issue with my 2011 13" MBA Ultimate. Whenever I resume from sleep, Safari, Chrome, Firefox and just about everything that requires scrolling is *extremely* choppy. I can get rid of the lag if I restart but I wasn't having this issue with my 2010 MBA 13" Ultimate on SL. I've reset the PRAM and SMC and I did a disk verify. Nothing thus far has worked. Is anyone else running into this issue? Has anyone found a fix? Thanks!
