    • 2f397aa15a13efbadf6c1bc378bb134ac1e655c5 (qtdeclarative/5.11, 26.4.2018, 5.11.1)

    Description

      Using Drag.dragType: Drag.Automatic triggers crash when drags are performed via touch.
      The same code with Drag.dragType: Drag.Internal does not trigger the crash.
      The dragged Item also does not move with the mouse when Drag.dragType: Drag.Automatic.

      I have attached a copy of the Call Stack and the offending QML code for your convenience.
