overlay deformation

I think I’ve spotted a bug.
I have some problem with the overlay scene.
When I start the game in blender everything’s right and beautiful.
But when I save as runtime… the overlay scene have one big problems.

It’s squished ! the camera think it’s perfectly square and then tries to show everything in the 16/10 window.

Is it a known bug ?
Am I so noob that I missed something ?

Here’s the blend file for reference.

Have a nice day !
