    Description

      Steps to reproduce:

      1. connect a second monitor to your X session
      2. move your Qt5 application window there
      3. disconnect the monitor

      When the X screen is removed, the application window disappears and won't show again.

      I've tested with Qt Creator and the secondary screen was placed to the left of the primary. I don't know if it makes a difference to the right.

      This does not happen with Qt 4.
