Shader to always show up, before lwrp worked 90% of the time, now works 40% of the time. How to?

Code (CSharp):

1. Shader "Custom/AlwaysShow"
2. {
3.     Properties
4.     {
5.         _MainTex ("Texture", 2D) = "white" {}
6.         _Color("Always visible color", Color) = (0,0,0,0)
7.     }
8.     SubShader
9.     {
10.         Tags { "Queue"="Transparent" }
11.         LOD 100
12.  
13.         Pass{
14.             Cull Off
15.             ZWrite Off
16.             Lighting Off
17.             ZTest Always
18.  
19.             CGPROGRAM
20.             #pragma vertex vert
21.             #pragma fragment frag
22.  
23.             #include "UnityCG.cginc"
24.      
25.             struct appdata
26.             {
27.                 float4 vertex : POSITION;
28.                 float2 uv : TEXCOORD0;
29.             };
30.  
31.             struct v2f
32.             {
33.                 float2 uv : TEXCOORD0;
34.                 float4 vertex : SV_POSITION;
35.             };
36.  
37.             float4 _Color;
38.  
39.             v2f vert(appdata v)
40.             {
41.                 v2f o;
42.                 o.vertex = UnityObjectToClipPos(v.vertex);
43.                 return o;
44.             }
45.  
46.             fixed4 frag(v2f i) : SV_Target
47.             {
48.                 return _Color;
49.             }
50.  
51.             ENDCG
52.         }
53.     }
54. }

Often when the object is below the ground the object will dissapear, some times when behind other objects it disappears for part of the time its behind them. I haven't been able to ever find a solution to always make the object show up.

On the material that uses this shader i've tried values from 500 to 4001 and seen no difference in behaviour, just for a complete test.

I've also tried setting ZTest to Off
Changing the Queue to Overlay :
Tags { "Queue"="Overlay+1" }

I don't care if I use this shader or not, but from the research i've done online I thought it was supposed to be how to make a magic always show this gameobject shader. I'm just trying to find a shader that won't have the objects sometimes dissapear.

Thanks
