Material render order issue Unity 5.3.5

Unity Engine
1

Look at this picture. The material to the left is from the same shader as the the one from the object to the right.
Behind is a mesh text that is suppose to always be rendered. The object to the right is a prefag.
If i reset the material it shows correct.

Is this a Unity bug or what is this?

Shader

    Tags{ "RenderType" = "Opaque" }
            Blend SrcAlpha OneMinusSrcAlpha Cull Back
            LOD 400   

CGPROGRAM
      #pragma surface surf SimpleSpecular  

      struct Input
      {
        float2 uv_MainTex;
        float2 uv_BumpMap;
        float2 uv_EmissionTex; 
        float3 worldRefl;
        float3 viewDir;
        INTERNAL_DATA
      };

    

      half4 LightingSimpleSpecular (SurfaceOutput s, half3 lightDir, half3 viewDir, half atten)
      {             

        half3 h = normalize (lightDir + viewDir);

        half diff;
        diff = max (0, dot (s.Normal, lightDir));

        float nh = max (0, dot (s.Normal, h));
        float spec = pow (nh*_Gloss, _Specular);

        half4 c;
        c.rgb = (s.Albedo * _LightColor0.rgb * diff + _LightColor0.rgb * spec) * atten;
        c.a = s.Alpha;
        return c;
      }

        void surf (Input IN, inout SurfaceOutput o)
        {
            half4 tex = tex2D (_MainTex, IN.uv_MainTex) * _Color;
            o.Albedo = tex.rgb;       
            o.Specular = 1;
            o.Gloss = 1;
            o.Normal = UnpackNormal(tex2D(_BumpMap, IN.uv_MainTex))* _BumpLevel;

            // Lumination system
            half rim = 1.0 - saturate(dot (normalize(IN.viewDir), o.Normal));
            float4 Tex2D1=tex2D(_EmissionTex,(IN.uv_EmissionTex.xyxy).xy);
            float4 Multiply0=Tex2D1 * _EmissionColor;
            float4 Multiply2=Multiply0 * _EmissionColor.a;

            if (_RimPower > 0)
            {
                o.Emission = _EmissionColor.a * _EmissionColor.rgb * pow (rim, _RimPower);
            }
            else
            {
               o.Emission = Multiply2 * _EmissionColor.rgb;
            }
            if (_Reflection > 0)
            {
                o.Emission += texCUBE(_CubeMap, WorldReflectionVector(IN, o.Normal)).r *_Color *_Reflection;
            }

        }

I dont think its the shader, because if i swap shader and back to this its back to normal. I also seen this problem with standard shaders.

My theory is that that the shader was altered after the material was added, and some fishy thing happen and didn’t get updated by the Unity engine.

I figured out what the bug is, shaders are not initialize properly. If you change the tag example { “Queue” = “Transparent”
You have to redo the material for it to initialize. Else nothing happens.

Please i want this fixed because i am doing allot of custom shaders. At least add a button
for initialize shader, reset is just not a good option for this. Thanks

Bump. I also see the this bug with SubShader { Tags{ “Queue” can not only happen when the shader is changed, but also just by scence load or prefab instance. Please make shader initialize correctly.

I have posted about this before, that if you assign a custom render queue to a standard shader, the editor will automatically reset the render queue if you change the shader in the editor. So if you assign something like 3002, then go assign a texture in the shader, the shader resets itself to 3000. This is happening in Unity 5.3.6.
