PostProcess material nodes broken in widescreen big FOV

I am having a problem with some nodes in post process with widescreen/non standard fov ( 5.3 ).

The world position is broken and so many nodes like CameraVector. Works fine in the editor viewport but not in standalone or play in new editor window.

This is the editor World position:

And this is how it looks ingame:

This is also how the camera vector looks:

This is the material:

There is clearly something broken, at the moment there is no way to get the camera vector in post process.
You can “avoid” the problem by setting this line in your DefaultEngine.ini.

[/Script/Engine.LocalPlayer]
AspectRatioAxisConstraint=AspectRatio_MaintainXFOV

Or by adding an inverted shpere with a huge scale like the skySphere, so the engine writes its world position.

Does anyone know if there is a proper way to fix this?
