The current header behaviour is described in the app design guidelines[1] (see "Overlay" section), and it's used also in the image viewer of gallery-app[2].

"The Header is made semi-transparent and the content sits beneath it. Developers can choose for it to be displayed constantly or hidden on timeout or tap."

We have chosen this behaviour since the default one seems not to fit perfectly with our navigation pattern (in a standard list view, the elements provided are somehow in a hierarchy - e.g. relevance, date, etc - so scrolling up the view is a less important action than scrolling down, but pages in a PDF documents has not that strong hierarchy).

I agree that this behaviour is a bit weird, since it's not much used in Ubuntu SDK apps, but, being "authorized" by the UI guidelines, IMHO this is not a real issue.

Anyway we're missing the "semi-transparent" part, and this may require to be fixed.

I've heard some different opinion on the implementation of the header, before choosing the current one, so I'm open to any further discussion on this.
