Segfault on Arch Linux

[sbomer]

Using https://aur.archlinux.org/packages/hardinfo-git/, I get:

Happy to provide more information. If it's relevant, I'm running a Wayland WM (with XWayland installed). The UI does render for a split second.

This is really weird. The place that calls gdk_x11_screen_get_window_manager_name() actually checks if the default screen is valid before. It shouldn't crash there. I'm also on Arch Linux and Wayland, with a GTK3 build, and I'm not seeing this.

What desktop environment/compositor are you using?

Interesting - this was using https://swaywm.org/.
