      Description

      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.
