[Theme: Minimal Georgia] Love it but one issue in header

I think this theme is great and I am using it, but I notice one issue, that only appears on tablets (Samsung Galaxy, for instance, or an iPad). The header bar that stretches across the top, for some reason, the background truncates on the very right side of the screen. But not on a desktop, you can only see the issue when viewing it on a tablet. To see an example of this, you can look at a demo of the theme at this link while viewing the theme on a tablet: http://www.truethemes.org/demo/

Or if you do not have a tablet, view the same link in a tablet emulator, such as seen at this link:
http://tablet-emulator.org/

I would really like to be able to manually fix this myself but I am not sure exactly where in the css or other part of the code to do so. Any ideas, from the developer or from someone else who uses it, greatly appreciated.
