Created attachment 8739808 [details] A screen shot STR 1) disable E10S 2) make browser width narrow to collapse sidebar in the content 3) open https://w3c.github.io/web-animations/#dom-animationeffecttiming-fill See attachment as a result. There are tons of below messages on console: [GFX3-]: FillGlyphs bad surface 1 [GFX2-]: DrawTargetCairo context in error state: invalid matrix (not invertible)(5)
https://drafts.csswg.org/css-animations-1/#the-animation-delay-property http://w3c.github.io/performance-timeline/#the-performance-observer-interface Other specs are not rendered correctly too.
Summary: https://w3c.github.io/web-animations/#dom-animationeffecttiming-fill is not rendered at all → W3C spec pages are not rendered at all
I can reproduce this with https://www.w3.org/TR/SVG/masking.html in a fullscreen browser (no need for "make browser width narrow" step). Matt, this is flagged as a regression from your bug 852754, and it's a pretty bad regression (making sites completely 100% unusable). Any chance you can take a look soon? Also, requesting tracking to be sure we don't lose track of this: [Tracking Requested - why for this release]: Serious rendering regression on important site (where web specs are hosted). Dogfooding bug for anyone who needs to read web specs (and has e10s disabled).

I can still reproduce the glitch(Bug 1265256 comment#0) on Windows7 with HWA and e10s both disabled. https://hg.mozilla.org/mozilla-central/rev/ae7413abfa4d3954a6a4ce7c1613a7100f367f9a Mozilla/5.0 (Windows NT 6.1; WOW64; rv:48.0) Gecko/20100101 Firefox/48.0 ID:20160419030312

A problem still there is that "W3C Editor's Draft" is not shown up while collapsing sidebar.
I'm going to close this bug up again. The thing in comment 10 was referring to bug 1265256 which has been reopened to track that issue.
