I don't think there is any reason for this to be marked security-sensitive. Unhiding.
Thanks for reporting this. Can you please load the same demo in Chrome Canary? Just to eliminate any Hardware problems that you might have. Also from the photo I see that some particles are jumping here and there, that is expected from this particular demo. (here is a short video of what the demo should do: https://dl.dropboxusercontent.com/u/109148197/WebGL2.0/Particles%20demo.mov).
I'll close this bug as Worksforme due to lack of information from the reporter. Feel free to reopen this or log a new bug if this is a real issue here.
