sniffnet Create event loop panicked (`winit`)

Is there an existing issue for this?

[X] I have searched the existing issues.

What's the problem?

latest release on crates and brew:

thread 'main' panicked at /home/linuxbrew/.cache/Homebrew/cargo_cache/registry/src/index.crates.io-6f17d22bba15001f/iced_winit-0.12.2/src/application.rs:119:10:
Create event loop: NotSupported(NotSupportedError)

Hey @ngmisl, this seems to be an upstream issue. The program is crashing at this line of the iced_winit dependency. And this is the method that's causing the crash.

It's pretty weird that you're the first one to face this problem. Can you please provide me with additional information about your OS and environment?

Oh.. I was stupid. Please ignore previous my comments. My Arch Linux was sever profiled, which does not have any GUI. So I installed and set up KDE plasma. After that I can see sniffnet is up and running. :)

after the installation and setup, I checked the value from $XDG_SESSION_TYPE. that is wayland. :)

My reference for installation and setup KDE Plasma is https://itsfoss.com/install-kde-arch-linux/

Hey guys, a new version 1.3.2 was released the last month.

Can you please try running it and let me know if the problem was fixed?

If it still doesn't work, try setting the environment variable ICED_BACKEND=tiny-skia and run the app.

If it still doesn't work, try setting the environment variable ICED_BACKEND=tiny-skia and run the app.

It was definitely fixed for me in the latest version. I can now inspect any adapters or specific hosts and nothing crashes anymore.
