Postprocessing SAO makes everything blurry and pixelated

Posts above were on a iMac tested Safari and Chrome need to test tomorrow again on iOS.
Right now im on a w7 PC Chrome/Firefox and the blurry and pixelated stuff is gone. FXAA seems to work, but now when I use SAOPass.OUTPUT.SAO I only see white, theres no ambient occlusion. Same on the sao threejs example I see only white when set to SAO

Im not getting the jsFiddle to work. How to include the threejs example files properly? Anyway thats basicly what happens. The models used are gltf’s exported from Blender. They are placed to form a shelf dynamicly.

Here is a live example on a test server where SAO and FXAA is enabled (meanwhile inactive)
