Steps to reproduce:
i opened my firefox browser and browsed this url http://toji.github.io/webgl2-particles/ as a part on working for QA test day
on opening that url there was on animation on the text WebGl2.The animation didn't play as it was expected it had visual glitches.
the text WebGl2 should have been displayed and animation should have played with no visual glitches or lags
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.
