User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:64.0) Gecko/20100101 Firefox/64.0

[Affected versions]:
- FX 64.0b3

[Affected platforms]:
- Ubuntu 16.04 LTS

[Steps to reproduce]:
1. Open Firefox with a new profile.
2. Go to https://playcanv.as/e/p/44MRmJRU/

[Expected result]:
- The page loads and you are able to play the game with no rendering issues or lag of any kind.

[Actual result]:
- 2 things may happen:

1. A yellow warning bar pops up warning you that "A web page is slowing down your browser. What would you like to do?". From this point on you have 2 options: "Stop it" and "Wait". None of them seem to do much to help the issue. 

2. The site loads and you can press "Start". When this does happen, pressing Start will give you the pointer control notification telling you that the site has control of your pointer. You should now be able to navigate through the game but nothing appears on screen except for a black screen. Sound is also coming through.

[Regression range]:
- Will look for a regression range ASAP

[Additional notes]:
- This works flawlessly on Chromium on the same environment.
- I have uploaded screenshots with the issues described in "Actual result" and a screenshot of the Graphics section from about:support.

I have added the screenshots in my drive since they're big and I couldn't upload them to bugzilla

Jeff: Can we have an owner for this?

We don't have bandwidth to address this for now.

Please narrow the regression range.
