I thought it was a feature at first, since OGL has the shader support while D3D doesn't. But as degasus mentioned (https://github.com/dolphin-emu/dolphin/blob/master/Source/Core/VideoBackends/OGL/PostProcessing.cpp#L157), it should be filtered. I could hackfix it adding glBindSampler(0, 0); and it seemed to work while using unit9 didn't. Weird...

Using CodeXL, I could see no issue with the samplers as none was bound to unit9 and last active texture was indeed GL_TEXTURE9. All of the samplers look bound to at least unit0 though which is why I tried that.

Time to track down the last build that worked fine...

Fifo thing
