What i ended up having to do is invert the x component of the uvs for the sky shader (however they are provided) and then flip the Right and Left passes. Its kinda hacky but it works. And much better to fix in the sky shader one time than in each of the reflection/refraction shaders. I've also updated the old reflection/refraction shaders to work without the X flip by default now.
