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.
