Pimax Crystal Guardian Rings

[Nuggetz]

I have a Pimax Crystal with which I am very happy with one exception. In the left lens only I can now see a couple of arcs of guardian rings which now acts as a distraction in the low fov. I have used the Pimax forum and contacted Pimax directly for a solution without success so far. With Pimax support I am about to rollback the Pimax Play and Crystal firmware but before doing so I thought I would ask the DCS community. 
 

As far as I know the Crystal does not use guardian rings and I don’t have SteamVR installed so chaperone rings do not apply. 
 

I have done the usual resetting, uninstalling and reinstalling of all relevant software including clearing out the PC registry without success. 
 

Does anyone have any ideas to help resolve this issue please. 
 

Note: Guardian rings in Pimax XR is set to off. 
 

Many thanks in advance. 
 

UPDATE: Faulty headset returned to Pimax replacement headset received- all good now.
