HTC Vive Pro.
All firmwares upgraded. Newest windows, steam VR and X-Plane.
Regular flights work perfectly, but when I go into flight school, then everything looks as if I did a normal flight. No instructions anywhere in the VR goggles. But when I take them off, then I can see that they are on the monitor.
On the monitor the game is running as if there was no VR going on at the same time: It's just the regular X-Plane with all instructions, and I can control the plane with the mouse...
