Looks like this is only occurring on NixOS: https://crash-stats.mozilla.org/signature/?product=Firefox&signature=libwayland-client.so.0%400xb989. Possibly because it has the new version but unlikely.

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Gtk' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

The bug has a crash signature, thus the bug will be considered confirmed.

I get more crash reports that contains libwayland in its signature. They all seemed new, so this is worrisome.

Martin, would you be able to triage this? Thanks!

They have different crash reasons and you need to exclude older versions.
bug 1802327 has been fixed. bug 1803016 is still there.

Both of those issues look different. I was not screensharing when this occurred and the stack traces look significantly different.

comment 0 has the same crash reason as bug 1802327. Please check if this has been fixed for you in Firefox 109 or https://nightly.mozilla.org.
