You can test the following link in Safari and Chrome: https://threejs.org/examples/#webgl_animation_scene Chrome renders correctly, Safari renders a white screen. We've noticed this on production projects and had to use {alpha: true} in the initialization to get the colors to render correctly -- although it still required additional workarounds in specific shaders to fully fix.
Also: We found this to occur on Nvidia cards (MBP 750M) but have also seen it on Iris Pro.

This should work now
