      When a dialog is hidden and reopened, the dialog turns blank.

      Step to reproduce :

      • Run CloseTest app
      • Click on Open Dialog button
      • Close the dialog with the window cross
      • Re-click on Open Dialog button
      • The dialog is totally blank

      Resizing the window turn it normal again.

       

      The same is working on Qt 5.13.0 and on Qt 5.12.3.
