GLSL errors in Internet Explorer 11 Preview
Some workarounds are noted here to help you get your GLSL code working with Internet Explorer 11 Preview.
Your GLSL program isn't compiling.
|struct support||Structures are not available yet||Rewrite code to not use structures.|
|Texture lookup in the vertex shader||Supported on specific hardware.||Use gl.getParameter(gl.MAX_VERTEX_TEXTURE_IMAGE_UNITS) to determine if vertex shader texture lookup is supported and adjust your shader conditionally.|
|gl_FrontFacing||Not currently supported.|
|#line support||Not currently supported.|
|GLSL extensions (such as OES_standard_derivatives)||Not currently supported.|
|Internal Linker Error||A shader failed to compile or link on provided hardware due to its complexity.||Try reducing the complexity of the shader so it can run on all hardware.|
|gl_PointSize||Implemented but value doesn't change.|
