No window is created on Wayland.

The code

As seen on docs.rs.

use winit::{
    event::{Event, WindowEvent},
    event_loop::EventLoop,
    window::WindowBuilder,
};

fn main() {
    let event_loop = EventLoop::new();
    let window = WindowBuilder::new()
        .build(&event_loop)
        .unwrap();

    event_loop.run(move |event, _, control_flow| {
        // ControlFlow::Poll continuously runs the event loop, even if the OS hasn't
        // dispatched any events. This is ideal for games and similar applications.
        control_flow.set_poll();

        match event {
            Event::WindowEvent {
                event: WindowEvent::CloseRequested,
                ..
            } => {
                println!("The close button was pressed; stopping");
                control_flow.set_exit();
            }
            Event::MainEventsCleared => {
                // Application update code.

                // Queue a RedrawRequested event.
                //
                // You only need to call this if you've determined that you need to redraw, in
                // applications which do not always need to. Applications that redraw continuously
                // can just render here instead.
                window.request_redraw();
            }
            Event::RedrawRequested(_) => {
                // Redraw the application.
                //
                // It's preferable for applications that do not render continuously to render in
                // this event rather than in MainEventsCleared, since rendering in here allows
                // the program to gracefully handle redraws requested by the OS.
            }
            _ => (),
        }
    });
}

When I build and run this on KDE Plasma (Wayland), the process is created, but the window is not. However, when I try again on KDE Plasma (X11), everything works as expected. I don't know where this could be going wrong if winit has both x11 and Wayland features enabled by default.

Just in case anyone asks; this is what the console looks like when I run the project on both Wayland and x11:

Finished dev [unoptimized + debuginfo] target(s) in 0.05s
