Safari Graphics Glitches

It is most prevalent on Facebook, whenever I scroll around, or typing something, the words might suddenly disappear, I need to point the cursor and press it for the whole words to show again. When I scroll around, it's also very laggy, even though Safari is the only thing on, and my MBP has an i7, which should handle a little web surfing like this with ease, so I figured it might be a Safari problem as I couldn't re-produce such problem on Google Chrome.

I do hope this gets fixed, as I want to keep using Safari on my Mac
