Shader Graph flattening / skewing objects

[eeeeeeeeeeeeeee]

Im trying to make a shader graph just rotate object on Y axis, for some reason it is skewing / flattening objects

This is the shader with the unity cube primitive

it does work perfectly with a mesh that is just a single grass blade, but I am sure it just works because it is already a flat mesh, i want this shader to work for any mesh

There is a Rotate About Axis node that does this: Rotate About Axis Node | Shader Graph | 17.6.0

Use the position in Object Space as input and (0,1,0) as Axis.

[eeeeeeeeeeeeeee]

Yeah but that is expensive since it probably performs all the matrix calculations for rotating as it does rotate all axis, I understand gpu accelerated for that but this shader is running on over 20 million meshes.
