vscode LSP panic in winit with WSL: `(libXcursor.so.1: cannot open shared object file: No such file or directory)`

[MrDwarf7]

Yes, you're welcome, thank you. 🦀

Step 1. Create Slint project from rust-slint-template

Step 2 (Optional). Cry a little bit because there's not a simpler way to get Slint support in Neovim via Arch.

Step 3. Use VsCode due to native extension support, open Ui folder and observe the beauty of correct syntactical highlighting.

Step 4. Compile a binary using cargo build --release --target "x86_64-pc-windows-gnu" Open compiled Windows 11 64bit .exe from within the WSL distro (Crossing the Windows/WSL barrier). Close compiled.

Step 5. Realize the text is tiny on your giant Samsung Neo G9 monitor and head over to the Ui file to add a font-size with 20.

Step 6. Get an error because you're a newbie to Rust language and haven't yet read the Slint document because you're too eager to play around and consider that Ui can't be that hard if you've spent the last 10 months choking on JavaScript.

Step 7. Using the Vs-Code Neovim plugin, and a hand-crafted variety of highly personalized key bindings unique to only my experience - Hit Ctrl+K to attempt to replicate hovering with a mouse and see what the error is. (Silently hoping it's not "Can't define null on undefined").

Step 8. Not profit. Slint crashes and prompts me to open an issue, which I do.

Step 9. Begin having an existential crisis as I've caught up to the story in real time, and I paste in the crash log from my terminal in VsCode, the inferior editor. It reads:

thread 'main' panicked at /home/runner/.cargo/registry/src/index.crates.io-6f17d22bba15001f/winit-0.29.4/src/platform_impl/linux/mod.rs:787:62:

The Slint Language Server crashed. This is a bug.
Please open an issue on https://github.com/slint-ui/slint/issues 

Step 10. Complete the convoluted and (hopefully amusing) re-count of my tragic experience leading up to a Rust-related LSP crash.

Observe! I present the offending code block. The stock slint rust template with a slightly syntactically incorrect piece of code.

import { Button, VerticalBox } from "std-widgets.slint";
export component AppWindow inherits Window {
    in-out property<int> counter: 42;

    callback request-increase-value();

    VerticalBox {
        Text {
            font-size: "16";
            text: "Counter: \{root.counter}";
        }
        Button {
            text: "Increase value";
            clicked => {
                root.request-increase-value();
            }
        }
    }
}

Not a neovim user myself, but did you try the steps explained here: https://github.com/slint-ui/slint/tree/master/editors#neovim

LibraryOpenError(OpenError { kind: Library, detail: "opening library failed (libXcursor.so.1: cannot open shared object file: No such file or directory); opening library failed (libXcursor.so: cannot open shared object file: No such file or directory)" })

This is a panic in winit (the library Slint uses to handle windows) and it says it can't open a required shared library. Arguably, winit should try to report the user better than panicking. But the fix here is to install the libXcursor library.

Similar to https://github.com/slint-ui/slint/issues/4185, the panic should be fixed in winit now, and if it remains a panic in Slint, it is #204
