Touch events on complex ui not always firing
I have a strange behaviour on my apps. Some mouse click events are not fired on the first time the area is clicked. Sometimes it needs 2 or 3 clicks till the mouse event fires. I have some little more complex uis with mostly a listview within it. The listview takes the scroll events always fine but for example the delegates do most of the time not react on the first click. Same is for components outside of the listview. This seems to happen primary when the listview was scrolled.
This happens on all my touch devices iOS and Android. Qt-Version is 5.3, and 5.4.
Has anyone an idea?
