Steps to reproduce:
- Set Graphics API to OpenGLES2 under Player Settings > Other Settings
- Build a project for iOS (with any backend Mono or IL2CPP)
- Run on a device

Result: See an error in the XCode log (full error in the attached file)

    It's June 2017 and I'm still getting the same error as everyone else on Unity 5.5.3f1 with an iPhone 6S. I have to use diffuse mobile errors to get good performance out of the game.

    Here's the error:

    -------- Shader compilation failed
    #version 100

    precision highp float;
    uniform highp vec4 _ProjectionParams;

    {
    highp vec4 tmpvar_1;
    tmpvar_1 = texture2D (_CameraDepthTexture, xlv_TEXCOORD0);
    mediump vec2 tmpvar_2;
    highp vec4 tmpvar_3;
    tmpvar_3.w = 1.0;
    tmpvar_3.xyz = ((xlv_TEXCOORD1 * (_ProjectionParams.z / xlv_TEXCOORD1.z)) * (1.0/((
    (_ZBufferParams.x * tmpvar_1.x)
    + _ZBufferParams.y))));
    highp vec4 tmpvar_4;
    tmpvar_4 = (unity_CameraToWorld * tmpvar_3);
    highp vec4 tmpvar_5;
    tmpvar_5 = (_PreviousVP * tmpvar_4);
    highp vec4 tmpvar_6;
    tmpvar_6 = (_NonJitteredVP * tmpvar_4);
    highp vec2 tmpvar_7;
    tmpvar_7 = (((tmpvar_5.xy / tmpvar_5.w) + 1.0) / 2.0);

    highp vec2 tmpvar_8;
    tmpvar_8 = (((tmpvar_6.xy / tmpvar_6.w) + 1.0) / 2.0);
    tmpvar_2 = (tmpvar_8 - tmpvar_7);
    mediump vec4 tmpvar_9;
    tmpvar_9.zw = vec2(0.0, 1.0);
    tmpvar_9.xy = tmpvar_2;
    gl_FragDepthEXT = tmpvar_1.x;
    gl_FragData[0] = tmpvar_9;
    }

    Still occurs in Unity 5.5.0f3 when building for android, could this cause this glitch? https://pbs.twimg.com/media/Czd5wX2XcAE9Sk-.jpg I was looking through the adb logcat for hints to this glitch and found this issuetracker

    This is not fixed in 5.4.3f1. I'm getting the same error as everyone else.
