WSL: Rerun native crashes on launch with Could not find wayland compositor

[jprochazk]

On WSL2, the native viewer crashes immediately on launch with "Could not find wayland compositor".

$ rerun

Error: winit EventLoopError: os error at /usr/local/cargo/registry/src/index.crates.io-6f17d22bba15001f/winit-0.29.9/src/platform_impl/linux/wayland/event_loop/mod.rs:81: Could not find wayland compositor -> os error at /usr/local/cargo/registry/src/index.crates.io-6f17d22bba15001f/winit-0.29.9/src/platform_impl/linux/wayland/event_loop/mod.rs:81: Could not find wayland compositor

The documented workaround of setting WAYLAND_DISPLAY= works, but we could at least try to improve the error message.

Tested on both rerun 0.16.1 and latest main.

fresh wsl install running pixi run rerun off main I get a similar, but not identical error:

Error: winit EventLoopError: os error at /home/andreas/.cargo/registry/src/index.crates.io-6f17d22bba15001f/winit-0.29.15/src/platform_impl/linux/wayland/event_loop/mod.rs:80: The wayland library could not be loaded

Running WAYLAND_DISPLAY= pixi run rerun gives me
Error: winit EventLoopError: the requested operation is not supported by Winit

After that I realized I didn't install any of the packages we ask linux users to install on https://rerun.io/docs/getting-started/troubleshooting (pretty bad user experience that this isn't printed :/)
Once done, I can no longer repro the issue at all and pixi run rerun just works Oo (restarted the terminal to be sure the env var didn't change for the session).

Can you check what happens when you go through the dependencies on our troubleshooting page if you haven't already?
