Which backend (OpenGL, Metal, Vulkan) / platform (macOS, Windows, etc) are you using?

OpenGL with Nvidia GTX 2060, i found it is a similar case as issue, scaleMatrix in light_reflections.fs cause a bad optimization by SPIR-V tool.

highp mat4 uvFromViewMatrix = scaleMatrix(res.x, res.y) * frameUniforms.ssrUvFromViewMatrix;

Isn't this also similar to this issue ?

I'm going to assume this is fixed because the spirv matrix assignment issue has been fixed.
