[wdv4758h]

I tried the current stable branch 97df73fe1f264f04cf6967fa5565d0ed820fed97 on Wayland (Sway 1.8.1). It crashed on start. However, I do find a fork of emulsion that works on my machine.

In case it helps in some ways. The Wayland/Sway working fork I found is this one.

@wdv4758h I think the Wayland crash is unrelated to this crash. I expect your crash should be fixed when I resolve #71.

I'm guessing you have to enable the wayland feature? Or does it work without?

Actually, both works, it works with or without wayland feature. Not sure what's behavior difference, but that repo works on Sway 1.8.1 out of the box. No crashing and can view images normaly.

Interesting, I'd have to look closer to see what changed. Thanks for the info!
