image::Handle::from_rgba not working

[German Laullon]

Is there an existing issue for this?

• I have searched the existing issues.

Is this issue related to iced?

• My hardware is compatible and my graphics drivers are up-to-date.

What happened?

I have this code:

use iced::{
    widget::{column, image, text, Column, Image},
    ContentFit, Length,
};

fn main() -> iced::Result {
    tracing_subscriber::fmt::init();
    iced::program("Iced example", Window::update, Window::view).run()
}

#[derive(Default)]
struct Window {}

#[derive(Debug)]
pub enum Message {}

impl Window {
    pub fn view(&self) -> Column<Message> {
        let pixels = [0xff, 1, 0, 0].repeat(10000);
        let screen = image::Handle::from_rgba(100, 100, pixels);

        let screen = Image::<image::Handle>::new(screen)
            .content_fit(ContentFit::Contain)
            .width(Length::Fill)
            .height(Length::Fill);

        column![text("Hello").size(50), screen, text("World !!").size(50)]
    }
    pub fn update(&mut self, _: Message) {}
}

What is the expected behavior?

I expect to have a "red" image between the two text.
