Safari has started display scrambled text on some websites. This only happens on certain site and in Safari. I've also noticed that the problem may appear in certain spots on the website, like the header, or an ad on Facebook.
Here's a screenshot of oDesk.com in Safari 5.1 (7534.48.3)
And here's a comparison in Chrome (13.0.782.112)
The problem only cropped up today but it's really frustrating as Safari is my main browser. I've tried deleting the Preferences file but that didn't solve the problem. Any help would be appreciated. Thanks.
