    Description

      Attached example program shows that when I show a QMenu via popup() in my widget event handler when receiving a QTouchUpdate event, I no longer receive a QTouchEnd event when I lift the finger from the touchscreen.

      Further, from this point on, I even do no longer get QTouchBegin events (instead I get a QTouchUpdate when pressing the finger again - which seems to be a follow up problem of the missing QTouchEnd event)
