Long time reader, first time poster. I received my rMBP about 3-4 weeks ago after having an issue with my older MacBook Pro's (The one right before the unibody generation) graphics card. Let's just say, there's no comparison between the two. Anyway, ever since updating to 10.8.2 I have been experiencing issues on safari where images don't load, typing lags/deletes itself, and safari itself just lags with loading/scrolling. Is this common issue, or am I dealing with a graphics card issue again? Please note that I have yet to see anything like this with any other application such as Pages, Calendar, or iTunes. (My 3 most used apps). Thanks in advance.
