Lens Matched Shading not working on Right Eye

I’ve been trying out the features in vrworks offered in the VRWorks 4.13 branch on github.
When I enable Lens matched shading the right eye seems to have left half and right half swapped; This happens in the vrfunhouse branch as well.
What I did:
In project settings I have ticked (on) : lens matched shading and multires.
in the console i type :
vr.multiresrendering 1
vr.lensmatchedshadingrendering 1
I get this result :

Does anybody else have this result ?
Did I forget something ?

I have tried the same thing with a vive and I do not get the bug.

I’m sure devs will enjoy using one SDK for one GPU brand and another, or their own code, for others.
