Whooooray, volume-key zooming! This mark the day when QML Browser become usable for everyday use, in my case. It works great - but, as expected, I've encountered few bugs: 1. Sometimes during fullscreen, all interface buttons stop working (the one for switching out of fullscreen, swiping from left for cursor or from right for history - nothing works), while rendered page can still be scrolled and used normally. What's interesting - if I get out of fullscreen by sending: Code: wmctrl -r :ACTIVE: -b toggle,fullscreen ... I can access the top-bar menu (new window, etc), but clicking those doesn't produce any results (they turn blue, indicated that they were clicked, but that's all about it). It looks like whole interface gets stuck. I haven't found a way to reproduce it reliably, but it happens relatively often.

2. Cursor mode works somehow strange. If I use it directly after swiping (without clicking on cursor icon to make it sticky), I can't highlight text for copying by using shift - it just keep scrolling page. Hoever, if I set it to sticky, all text that it hover over gets highlighted, even without holding shift.
3. As for the issue reported by marmistrz and explained by Copernicus, it is also perfectly reproducible without switching user agent, as long as page is still loading. If it stops loading (either by itself, or via cancelling), issue disappears.
