This is the fourth most common crash on the October 2 Windows Nightlies. It looks like a grab bag of different failure reasons, though this OOM one is the most common. Lots of WebGPU demos in the URLs, as you'd expect. I don't know if it is particularly actionable, but there's no open bug on file, so I thought I'd file one if there's something we can do here.
