    Description

      This is seen when using a QML MouseArea to capture the mouse/touch events using onPressed and onPositionChanged.

      In the attached example the mouse area is used to draw on a canvas as this is the scenario in which it was first seen.

      On a tablet running the app use a finger to activate the MouseArea functionality drawing on the canvas and continue to do so (i.e. keep finger pressed on the screen) while rotating the device.

      Once the screen has rotated the mouse area will stop functioning and it is no longer possible to draw on the canvas.

      Note: I have found that it is possible to work around this by adding an Item element inside the MouseArea. See the main.qml in the example and uncomment the Item at the end of the file.

          • P1: Critical - Urgent and Important, will STOP the release if matched with set FixVersion field. This includes regressions from the last version that are not edge cases; Data loss; Build issues; All but the most unlikely crashes/lockups/hanging; Serious usability issues and embarrassing bugs & Bugs critical to a deliverable. This is the highest possible priority for requirements.
