[Jeff Muizelaar [:jrmuizel]]

This is rare. Not blocking.

Comment 2

[Pascal Chevrel:pascalc]

We have a big spike of this signature in nightly since build 20191028094851 with this changelog:
https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=d31698ac05594dddbceba44fa99aebc97e1a8a50&tochange=9277be3613ca5109ae4007a512ee75856f8f1120

2 webrender bugs were in this window: bug 1591346 & bug 1590284

Comment 3

[Glenn Watson [:gw]]

I suspect this will be fixed by https://bugzilla.mozilla.org/show_bug.cgi?id=1592121 when it lands. However, if we have a URL / repro, I can confirm that with the local patch.

Changing the priority to p2 as the bug is tracked by a release manager for the current nightly.
See What Do You Triage for more information

Comment 5

[Julien Cristau [:jcristau] (back April 22)]

The spike from October 28/29 nightly builds seems to have gone away after that, and this has gone back to a low crash volume.

Comment 6

[BugBot [:suhaib / :marco/ :calixte]]

Closing because no crashes reported for 12 weeks.
