I have samsung odyssey, while playing a game , from the desktop viewer to full screen game (it hooks to the game), if my head remains centered for ~30 seconds (haven’t timed it), steam loading screen blackens everything, I have to move my head so I can go back to the game.
I have a tape on the sensor so it stops switching the keyboard, mouse input.
Removing the tape from your sensor might help. vorpX is supposed to go to a idle state when SteamVR reports the headset to be idle. Maybe your taped sensor causes wrong readings in that regard.
Let me know if the issue also occurs without the tape.
