Do you know what causes these issues and do you see any chance that Qt5/QtQuick2 wouldn't suffer from them (if any custom item is implemented using scenegraph)? I was able to compile the hildon components for Qt5 (with parts commented out, http://wiki.maemo.org/Qt5-Maemo5-Development/WhatWorks) and would like to try Alopex, too. Is this https://github.com/qwazix/qmlmozbrowser the current git for Alopex?
