I upgraded my mid-2008 Macbook Pro this week.  I went from the last non-unibody model to a Retina MBP 15".  I did not move my old computer over, however: I am simply installing apps and moving docs as needed.


I mention all of this because I am encountering a strange issue in Safari: as I browse, my screen will beome covered with blocks of blank white squares.  Here's a recent example from GMail:

As you can see, the content beneath the white square begins to show itself as I pass the cursor over certain aspects of the page.


This does not happen exclusively in GMail.  I've seen it across my web browsing.  It also occurs in text windows: as I type, the most recent word will sometimes disappear -- it's still there, but I can't see it unless I pass my mouse over it.


Any clues as to what could be causing this?  This was not a problem I had on my old Macbook.  I am guessing and hoping that it's software, not hardware, related.


I am on Safari 6.0.2 and OS X 10.8.2.

MacBook Pro, Mac OS X (10.5.4)
