1. Install Qt and Qt Creator using the Online Installer.
   Install all the needed packages or you'll run into QTBUG-140635.
2. Start Creator from the installation.
3. From Creator's "Welcome" screen, open the "XR physics-base teleportation demo".
4. Click "Configure project".
5. After Creator finished configuring the project, click the "Run" button.
   The demo doesn't show properly:
   
   In Creator's "Application Output" view, I can read:

   QML debugging is enabled. Only use this in a safe environment.
