Quest Pro controller tracking issues in DCS only

[Ratfink]

I have the Quest Pro now (upgrade from Rift S and Quest 2), and think it's a great headset for DCS over link cable.

I prefer to use the Quest hand controllers for clicking around the cockpit, but with DCS the right controller keeps disappearing and a message pops up from Quest saying controller cannot be tracked. A brief nudge, and it's back.

Sometimes the right hand appears floating by right hand side of cockpit for no reason, which I thought may be as I have the Quest pro set to use hand tracking and it seems to match the physical position of my hand on the TM WH F-18 joystick I have. I have turned off hand tracking but it still does it.

I have no other issues with the tracking of the controllers otherwise, this only happens in DCS
