I'm on a dual GPU system running Linux + bumblebee. When using the Sandy Bridge GPU, I also see all black with only the lighting highlights visible. Just tried again with the nVidia GPU and it worked fine. I really like WebGL, and I want it to succeed, but for this to happen developers are going to have to make sure that their code works on reasonably low end hardware (i.e. integrated graphics). This sort of GPU inconsistency is so common with WebGL right now that it reminds me of trying to browse the web on Linux circa 2000. Not a pleasant experience.
