OpenVR Driver and Stencil Mesh problems

I’ve sent a request via support already, however in the meantime is there older PiPlay downloads that would perhaps help me right now.

My problem is a resent update to Lockheed Martin’s Flight Simulator (P3Dv4.3) caused a black frame to appear across the viewing area. Support from Lockheed Martin suggested the fix must be made to the OpenVR drivers.

LM say it appears the headset is returning a bad stencil mesh in the OpenVR driver and needs updating.

I have no idea what this means but does someone know if an older version of PiPlay will help?
