           Summary: WebGL in Safari 6 DP2 on Lion 10.7.4 on Retina MBP
                    crashed entire system
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh Intel
               URL: http://aerotwist.com/tutorials/creating-particles-with
                    -three-js/demo/
        OS/Version: Mac OS X 10.7
            Status: NEW
          Severity: Major
          Priority: P2
         Component: WebGL
        AssignedTo: webkit-unassigned at lists.webkit.org

This could be related to the new Retina MBP graphics architecture, I've no idea. But going to this page:

http://aerotwist.com/tutorials/creating-particles-with-three-js/demo/

…first resulted in nothing, so I looked at the console in the (awesome new) Web Inspector. Noticed that there was a WebGL error (presumably WebGL, if disabled, still returns true on certain tests for it?), so then I enabled WebGL in the Develop menu. Reloaded the page, the particles showed up fine, and then I started clicking in the Canvas element to see if the particles did anything in reaction to that. I may have clicked and dragged a bit, but in any case, shortly after this interacting part the rendered particles started glitching (looping a set of 10-15 frames over and over), and then my cursor became a beachball, the entire system stopped responding, and I was forced to hard reboot.

I’m a little hesitant about doing any further testing with WebGL right now, given that I’m using a DP release that’s understandably not as stable.
