      2. Select Elem1 in grid
      3. Push "Add/Remove 3d widget" button. (openglwidget is apper on right)
      4. Push button again. Widget is removed.
      5. Select Elem3 in grid.
      6. Push button. (openglwidget is apper on right again)
      7. You see that grid is not properly repainted. See attached screenshot.

      Also this bug apper in other situations and other widgets but I can make demo project for with this. Also when openglwidget is created main window is flicker.
