Incorrect IN.normal on android

Hello, I am using default unlit shader in unity 5.3.6 (below in CG version).

• so vertex shader is defined as v2f vert (appdata IN) { ... }
• in Editor everything works, IN.normal is for every vertex different
• on Android, IN.normal seems to be 0,0,1 for whole model
• I am using render texture inside of Canvas (and second camera) to render it

Screenshots of normals: Editor, Android

Edit: created issue https://fogbugz.unity3d.com/default.asp?956667_2rfjik4okkiii57r

 

Hey,
Did you manage to solve this?
