SEGV whenever other outputs change

[colemickens]

1. I was VNC'd into my laptop running Sway. At this time, the KVM was not on the laptop, so the only output was HEADLESS-1.
2. The KVM switched back to the laptop, enabling the other output.

At this point my VNC session crashed. Sway kept running and I was able to just restart wayvnc, but it would be nice if it didn't crash of course.

Pretty sure this is solved by #201 - Please reopen if not.
