      Description

      Showing a GUI application with `showMinmized()` doesn't work on Ubuntu 18.04 and the window is displayed on the screen as if I started it with `showNormal()`.
      Note that it works fine on Ubuntu 16.04.

      I found that if I execute `mainWindow->showNormal(); mainWindow->sesWindowState(Qt::WindowMinimized);` the window is minimized.

      Steps to reproduce this issue:

      • open the "Main Window" example
      • change `mainWin.show();` in `main.cpp` with `mainWin.showMinimized()`
      • recompile and run
        -> the window is visible at start
