i have add a depth write in the spine-skeleton.shader already
(i didn't make a new shader because i want it to replace the default)
Shader "Spine/Skeleton" {

[HideInInspector] _StencilRef("Stencil Reference", Float) = 1.0
[HideInInspector][Enum(UnityEngine.Rendering.CompareFunction)] _StencilComp("Stencil Comparison", Float) = 8 // Set to Always as default
// Outline properties are drawn via custom editor.

[HideInInspector] _OutlineColor("Outline Color", Color) = (1,1,0,1)

CustomEditor "SpineShaderWithOutlineGUI"
}
it works for most spine resoures,BUT rare spine resoures have layer flicker during rendering
i don't know why it is
