The Bugbug bot thinks this bug should belong to the 'Core::Graphics: WebRender' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

I don't think it needs tracking for our releases, we have only 17 crashes across channels over the last month, all of them on Ubuntu 14.04 which is a very old EOL OS version and almost all crashes are from the same user. It's likely that recent video drivers are not available by default on this old OS.

So feedback from Canonical is:

The other one can be safely ignored if it's reproducible only on 14.04 (because it's EOL and there's no extended support for desktop).
