Hi, I have created a bug report with a Qt based example that allows to reproduce this bug on a touch screen.
https://bugreports.qt.io/browse/QTBUG-64116 <https://bugreports.qt.io/browse/QTBUG-64116> I would like to ask everyone that has currently applications that require this kind of embedding to up-vote this ticket as it has been immediately closed and marked out of scope apparently without a proper evaluation. I truly love Qt and many of you here know how much, but it is kind of annoying to have to contribute to fix show stopper bugs on a licensed product. Thanks!
