      This is a subtask of QTBUG-36935

      Take the qquickwidget example and replace the QML with:

      import QtQuick 2.1

Canvas {
    objectName: "TimeDisplay"
    contextType: "2d"

    onPaint: {
        context.fillStyle = "green";
        context.fillRect(0, 0, width, height);
    }
}

      Then resize the quickwidget inside the MDI area. At certain sizes persistent visual artifacts appear. See the screenshot.
