Bug report - Half transparent materials leak Passthrough layer over solid objects

OVRManager.eyeFovPremultipliedAlphaModeEnabled = false; // change to true

I set this to TRUE. This line was in PassthroughFader.cs (MRMotifs) but also other examples might have it.
Doesn't fix all issues but I had hand rays that were not visible at all if they were not over opaque geometry.
What it's supposed to do (from: here ) : 

Disabling eyeFovPremultipliedAlphaModeEnabled switches from premultiplied alpha blending to standard alpha blending. Premultiplied alpha blending can sometimes cause visual artifacts, such as flickering or halo effects, especially when dealing with semi-transparent pixels or certain lighting conditions. By disabling it, you will use standard alpha blending, which may handle these situations better and result in smoother visuals.
