(NGUI) display a charactor with a surface shader , on Android platform some mobile phone will shake the screen
there is a part of the surface shader,please help me find issue in this shader that create this question !!
Shader "ActionX/Actor" { Properties { //主纹理 _MainTex ("Base (RGB)", 2D) = "white" {} //主颜色(用于发色) _MainColor ("Main Color", Color) = (1,1,1,1) //纹理颜色置灰 [MaterialToggle] _ToGray ("ToGray", Float) = 0 //开启纹理叠加 [MaterialToggle] _OpenTO ("OpenTO", Float) = 0 //叠加的纹理 _TextureOverlay ("Texture Overlay", 2D) = "black" {} //开启颜色叠加(用于虚化) [MaterialToggle] _OpenCO ("OpenCO", Float) = 0 //叠加的颜色(用于虚化) _ColorOverlay ("Color Overlay", Color) = (1,1,1,1) //叠加的百分比值(用于虚化) _OverlayValue ("Overlay Value", Range(0,1)) = 0 //开启发光 [MaterialToggle] _OpenRI ("OpenRI", Float) = 0 //外发光颜色 _RimColor ("Rim Color", Color) = (0.5,0.5,0.5,0.5) //内发光颜色 _InnerColor ("Inner Color", Color) = (0.5,0.5,0.5,0.5) //发光强度 _Power ("Power(0-10)", Range(0,2)) = 2 //环境光颜色 _AmbientColor ("Ambient Color", Color) = (0.509,0.509,0.509,1) [HideInInspector]_Cutoff ("Alpha cutoff", Range(0,1)) = 0.5 } SubShader { Tags { "RenderType"="Opaque" "LightMode"="Always" } LOD 200

Shake the screen : when I Open a UI with a charator the screen will repeat open /close ui , only some moblie phone will show this
