--- Comment #2 from Renn <gymo27...@mozmail.com> ---
I was looking at the source code for the crash line -- unfortunately the source
I was looking at is not 1:1 line number accurate, so I don't actually know
where in the ::waylandScreen() function it's crashing, but I suspect it may be
the assert.
Here are some additional logs from journalctl that may be helpful.
