Equirectangular photo mapped into a sphere

Hello,

I want to create a simple VR application.
I have a cardboard camera at 0,0,0.
A sphere is at 0,0,0 with a scale of 10,10,10.

On this sphere, I have a material.
The texture is an equirectangular photo (working fine on other apps)
I have a shader (found on the web) to create a projection of equirectangular photo inside my sphere.

It works, but at the top and the bottom of the photo, the render is distorted.

Anyone has a solution for that?

Thanks !

same issue for me
