Mobile display not working

Hi all,

It seems that my frontpage is loading in a different view on mobile devices. The panel pictures should be rolling like they do on the desktop version. On an Ipad it shows black parts of the site when I scroll down or up.

I have the Jetpack plugin running, but already disabled the mobile enhancement.

Any other suggestions?
