I have an issue with a webgl shader that I've determined is related to ANGLE because it only occurs on Windows in Firefox or Chrome, and it doesn't happen if I force opengl (chrome --use-gl=desktop).
I've created a jsfiddle that shows ANGLE-generated HLSL of my custom shader. (for hlsl conversion to work in this jsfiddle, you must run chrome with --enable-privileged-webgl-extensions, or just see my gist of the output)
So I have working glsl and the generated hlsl compiles but doesn't do the same thing. The symptom is that on Windows, the vertices appear in correct initial locations, but do not move although I change the uniform jed. I can't find the bug in the generated code.
Any tips for debugging problems like this?
