I believe I have found the issue, or at least pinpointed how and why the shaders are diverging on OpenGL versus DirectX 11. I should have a fix for the HQx issues shortly, and I'll be doing a presumptive fix to other shaders by applying the same change to the rest of the current shader library. I'll let you know when it goes in, do let me know if there are any other shaders that are outlandishly wrong.
