Hi. Yeah, that behavior was annoying, so in order to fix it you need to remove your background from Special:ThemeDesigner, then in the Wikia.css add something like this:

html { /* Fixes background in Android versions of Chrome and Opera */ height: 100%; width: 100%; } body.mediawiki { /* Don't remove the class or the background will appear in message boxes for anonymous users */ background: #000 url("http://vignette2.wikia.nocookie.net/shingekinokyojin/images/0/0f/Wiki_background.jpg/revision/latest?cb=20160615104927") no-repeat fixed center top / cover !important; }

You can see that the url is our background which I uploaded to the wiki as a regular image: http://vignette2.wikia.nocookie.net/shingekinokyojin/images/0/0f/Wiki_background.jpg/revision/latest?cb=20160615104927
