    Description

      QDesktopWidget::primaryScreen() should return the primary screen. I changed the primary screen to my second monitor with xrandr, but QDesktopWidget::primaryScreen() always returned the old stored value and never updated with my changes.
      The primary screen might be changed. QDesktopWidget should be aware of the change and update the value accordingly.
