MRC video has shift (Hololens using HoloJS)

[nosy-b]

Hi!
I'm trying to record a demo using the Hololens and HoloJS with angle-Holographic branch and I got a parallax effect when I activate the MRC, possibly due to focus point as you can see in the image. I try to draw as far as I can from the Hololens (50cm).
It works fine through my eyes but I always have a shift in the video recorded via mrc. (The red contours are Hololens projection)
Following the documentation (https://docs.microsoft.com/en-us/windows/mixed-reality/mixed-reality-capture-for-developers#what-to-expect-when-mrc-is-enabled-hololens-specific) I looked to create a focus plane at 50cms but didn't see any change.
Or is it just the mid View matrix that is not well computed? How can I force a translation? It seems always shifted from 4 cms down-right
What is the view/projection matrix used when activating MRC?

Thank you!
