Another interesting observation with http://www.ceskenoviny.cz/zpravy /francouzska-justice-obvinila-16letou-divku-z-planovani-teroru/1379685: as soon as I scroll on this page (by dragging a finger on a phone or using the mouse scroll wheel on desktop), the contents of the title element change, so

I’ve done some profiling on my arale and I’ve found out a few interesting things: - there’s an urlChanged handler in NavigationBar.qml¹ that’s triggered with every load event, and it’s costly - the loadEvent and titleChanged handlers in Browser.qml² are expensive too, because they cause

@Olivier Tilloy: I've just asked my friend to test this on Android (Google Chrome) and was told the website (both the links I posted above) work just fine there, no problems with scrolling at all. I do no longer poses any Android (or non-Ubuntu) device so I can't test this on my own unfortunately
