I've tested a few different options in the theme, but still haven't been able to reproduce the problem while in Chrome (Win8).
I have a few questions...
Under Graphene Theme Options > Display, do you have anything entered in the Custom CSS box?
Under Advanced Options, do you have anything entered in the Custom
<head> Tags box?
And what's visible under Move generated CSS?
Do you have Show social sharing button enabled under General > Social Sharing Buttons?
Is Adsense enabled? General > Adsense Options
