AdvPDFViewer and touch

Hello,

if I load a PDF with several pages (10+) in AdvPDFViewer and scroll on a touch screen, nothing is displayed after a few pages.
The pages are only reloaded when I use the scroll bar.

The swipe movement is trying to load pages on demand. So the behaviour you see is the pages are being loaded in the background, but have already been scrolled out of view. To make the pages load that are actually in view, you can do a touch scrolling gesture and then stop the touch scrolling by tapping the screen once, that should stop and load pages currently in view.

The problem is that when scrolling stops, nothing happens. The pages never load. The display area remains gray. Even if I scroll forward/backward again, nothing loads.

Pages only load again when I use the scroll bar on the side.
