This crash seems to have been around for a while but I only noticed it today doing nightly crash triage. Several comments point to the crash happening on https://www.flightradar24.com but there's also several URLs pointing to dashboards of some kind (all behind logins, so not publicly available).

I had a crash with the same signature. In my case it happened when interacting my LAN-local grafana dashboard. As mentioned in 1870618, I was getting a lot of tab crashes, but at some point the whole process crashed too. I turned off hardware accel to work around it for now.
