.12] Low FPS on Web GL 2 .0 demo
[Affected versions]: - latest Nightly 52.0a1 - latest Developer Edition 51.0a2 [Affected platforms]: - Mac OS X 10.12 [Steps to reproduce]: 1. Start Firefox 2. Visit http://toji.github.io/webgl2-particles/ [Expected result]: - Demo is properly displayed. [Actual result]: - Very low FPS while loading the demo. Same thing happens on the other demo from toji.github http://toji.github.io/webgl2-particles-2/ [Regression range]: - Not sure if this is a regression, will investigate further. [Additional notes]: - On Firefox Developer Edition many glitches can be seen, but the same low FPS can be seen: https://dl.dropboxusercontent.com/u/109148197/WebGL2%20glitch.mov
Forgot note: Using Chrome Canary, the above demos are played nice and smooth.

Narrowed nightly regression window to [2016-08-02, 2016-08-03] Last good revision: ffac2798999c5b84f1b4605a1280994bb665a406 (2016-08-02) First bad revision: 6608e5864780589b25d5421c3d3673ab30c4c318 (2016-08-03) Pushlog: https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=ffac2798999c5b84f1b4605a1280994bb665a406&tochange=6608e5864780589b25d5421c3d3673ab30c4c318 Mozregression points me to bug 1274626 but I'm pretty much sure that it isn't right. I also spotted a few WebGL related bugs in the above pushlog: bug 1289655 and bug 1290987 that might be more accurate culprits.
It's likely 1289655, but I would like more information before diving in myself.
Depends on: 1289655

The fix for bug 1309643 should be shipping in 51+ now - can you please test them and see if this is better now?
Just verified across latest builds (Fx 51 beta 11, latest Developer Edition 52.0a2 and latest Nightly 53.0a1), that the demo is working as expected.
