John, if you disable Fisison and WebRender, does the crash still happen? Also, do you know of any specific page you are looking at that causes it, or any specific action that can be done to reproduce it?

Did this problem only start recently? Do you know which versions might be affected by this - only 78, or also earlier? If it's only 78 nightly, do you know approximately what day the problem started on?

The crash stack in the report itself is a bit bare and is hard to pin-point what's going on from that alone.

The component has been changed since the backlog priority was decided, so we're resetting it.

Lee, I'm sorry but I don't have much more information than what I have already given, as I am having trouble replicating the crash, and have not experienced it since. Obviously, as I have not been able to replicate it even with Webrender and Fission, I am unable to tell if disabling Webrender or Fission would affect the crash.

I was doing general browsing that included Reddit at the time, but I have not been able to come up with a site that specifically replicates the crash.

It is definitely a recent crash on Nightly, as I had not experienced it prior to the crash report being sent with 78.

I have, however, also experienced a further shutdown crash with ID 5a826936-a806-4a05-84bb-da6820200529. Not sure if it is related.

Happy to give any further info or go through further debugging steps if you have any further suggestions or requests that may assist. If I can replicate I will try disabling webrender and fission.

Sorry for the bugspam, but going back further it appears that the following crash reports may be related and that this problem may have been occurring longer than I thought:

These crashes occur on Wayland and X11.
