Comment 1

[Natalia Csoregi [:nataliaCs]]

:glandium could you possibly check this out?
Could it be caused by Bug 1726476?
Thank you!

Comment 2

[Sebastian Hengst [:aryx] (needinfo me if it's about an intermittent or backout)]

It's from bug 1724535 - the last modified file mentions the Canvas: WebGL from the error log.

This blocks updating dependencies and hence will likely get backed out.

Comment 3

[Alexandru Michis [:malexandru]]

Should be fixed by the backout of Bug 1724535:
https://hg.mozilla.org/integration/autoland/rev/2374a282fbbb201d2bc1fd39c7dcbf0dab568bb5
