I found this error in Google Chrome, which I cannot explain.
Fonts that are loaded for text sometimes change for some reason.
Here is a screenshot of the original font when loading the web page:

Here is what I see after a while:

When I start to scroll the page, the font returns to its normal state.
Does anyone know what is going on?
I have also seen this on many other sites. And even on my own web pages.
I am using Google Chrome version 31.0.1650.57 and I am on Mac OS X 10.9.
A screenshot is provided on the DropBox documentation website.
