Windows 8: When touching a mouse area in Qt Quick 2 then there are problems with the events that are generated from it as they are not correct or in the wrong order.
This is related to
QTBUG-29946 which solved this in some cases, the problem still exists for Qt Quick 2 but works fine in Qt Quick 1.
It will get two clicked events when a touch screen is involved. All that is needed is for something like:
to be used and it will output the message twice when clicked once on a touch screen.
In other similar case, if a pinch is performed then it will output a click event after the pinch has finished sometimes, this seems related to the above situation too.
