[Note]:
-

[Affected versions]:
- Fx 64.0b3

[Affected platforms]:
- Ubuntu 16.04 LTS

[Steps to reproduce]:
1. Open Firefox with a new profile.
2. Go to about:config and set "layers.acceleration.draw-fps" pref to "true".
3. Go to http://toji.github.io/webgl2-particles/

[Expected result]:
- The animation plays back flawlessly, without any lag or visual glitches

[Actual result]:
- The animation plays back at 1-5 fps. It's very slow.

[Regression range]:
- This seems to be a regression since I've tested it on Fx 57.0b1 and it worked better. I will do a regression range ASAP.

[Additional notes]:
- This works flawlessly on Chromium on the same environment.

I don't see anything in that large regression range. Please reduce further.
