I am very frequently hitting this assertion

In particular I get this 100% reliably while starting up the current tip with webrendest + layers-free. Inability to reproduce with nightly suggests my local build has something funky in a cache somewhere? 

I've also seen it a few times while opening tabs, but at the time I thought it was crashing due to the patches I was working on.

That would imply it is using a font that it failed to actually send over first, which should almost never happen. Do you have a test case that can reliably reproduce the issue?

I don't have a simple/clean reproduction. I just:

I added some event logging, as it seemed we were often crashing concurrently with font update notifications.

It appears something installs a bunch of Noto fonts on startup, which repeatedly clobbers the font whole font cache, which races with us rendering the first frame.

Ouch. This is a result of the patch in bug 1392659, which activates a bunch of fonts shipped for "Language Support" on macOS. We may be able to optimize this so that they're all activated in a single batch, though, which I'd assume will be much more efficient. I'll look into that...

https://github.com/servo/webrender/pull/1664 was picked up in 1397831, so the crash is fixed. I'm resolving this bug.

Jonathan, do you want to file a new bug for the optimization idea from comment 6?
