ISSUE DESCRIPTION

MSFS 2024 post-SU5. Quest 3 VR via Virtual Desktop / VDXR Aircraft: default Microsoft/iniBuilds A320neo Start on runway, ready for takeoff No GSX, no toolbar panels, no third-party aircraft Before takeoff: Airbus FCU push/pull knob interaction works in VR Rejected takeoff while remaining on ground: push/pull still works Normal takeoff: immediately after liftoff, push/pull knob interaction stops working in VR After failure: loading any Airbus aircraft still has broken push/pull in VR 2D/monitor mode still works Only restarting the simulator restores VR push/pull interaction

The trigger appears to be the aircraft transitioning from on-ground to airborne. A rejected takeoff while remaining on the ground does not break the function; actual liftoff does.

VR runtime: Virtual Desktop / VDXR
Headset: Quest 3
Cockpit Interaction System: Legacy tested; Lock mode also tested and does not resolve
MSFS launched normally, not as admin
Failure persists across airbus aircraft until simulator restart

FREQUENCY: Consistently every time.

REPRODUCTION STEPS

Please list clear steps you took in order to help our test team reproduce the same issue:

  1. Load aircraft/flightplan and start either at gate or ready for takeoff. Canned airbus A320 neo (Microsoft/Inibuilids).

  2. Check push/pull knob functions, specifically altimeter knob to move to STD mode and back in 2D mode. Works as expected.

  3. Ctrl+tab to launch VR, Repeat step 2. Knob still works as expected.

  4. Initiate take off and right after take off in VR mode, altimeter knob stops working. Go back to 2D mode and knob works as expected.

  5. Reproducible in any Airbus aircraft with pull knob function. Happens in 3rd party Fenix aircraft as well.

  6. Load any airbus aircraft without restarting sim and this function is now broken. Only reproducible once sim is restarted.

  7. Anyone with other VR setup, please test this and reply here. It will help if this is a broader issue.
