Trying to use the SharePoint 2013 Enterprise wiki's and I've encountered a couple of bugs.
1. The Page Rating and Categories right column will display over the top of page content if the window isn't wide enough to accomodate both. This happens in all browsers when there is an image in the wiki page like the screenshot below illustrates.
2. When you click on a Category you are brought to the System Category page (_layouts/15/Categories.aspx), this page displays all pages which have that tag. The problem is the list of pages start displaying underneath the left nav. This can become
especially problematic if you are using metadata navigation in your wiki:
