What's wrong in the first case? The only thing that seems different is the navigation pane.

I had the same problem when I did an upgrade to 8.1 from 8. I think the video drivers from Win 8 caused it. I went and did a clean install of 8.1, and installed the Drivers made for 8.1 by Nvidia and haven't had a problem since.
