Strange view with iOS 8 devices

Hi there,

with our iOS 8 devices the SharePoint 2010 delivers a stange view. The content stays the same, but the horizontal and vertical navigation look strange. Some items in the horizontal navigation cannot be clicked.

Look at this screenshot. On the top you can see the broken view with iOS 8 devices. Below is the normal view. How can I achieve the normal view for all devices? I tried disabling all mobile views, but iOS 8 devices still get this strange view.
