view space behaviour on editor


I try to create a simple matcap shader.
But I have some issue with the transform Tangent Space to View Space. It works fine on the material editor, but it’s weird on perspective view.
I rotate the camera all around a simple sphere, normally View Space representation must not move, but currently on editor we can see some rotation, view space seems to not follow my camera.


thanks in advance for your help.

Up, I’m really need to fix this behavior or know how to deal with,

I can’t think to be the only one, who have this issue…

I have follow this thread :

And that’s my result with this matcap when I orbit the camera :

Please tell me what’s wrong, thx
