    v3 v4  
     1= Fixed disabling vsync so mirroring to desktop does not cause stutter =
    12The openxr rendering flickers using Quest Pro or Quest 2 with the Oculus OpenXR runtime when desktop mirroring is used on vive.cgl.ucsf.edu with Quadro P6000 GPU.  Tests show that the mirror drawing does not cause the flicker if the OpenGL swap buffers call is not made, and that with no mirror drawing it still flickers if swap buffers is called. So it appears that swap buffers is causing the flicker.  With the Vive Pro headset and OpenXR steamvr runtime there is no flicker with mirroring on.  So it seems the problem is specific to the Oculus OpenXR runtime.  I also tried drawing the mirror window before releasing the right eye swap chain texture, but still the swap buffers was done after the release, and that also flickered.
