Bevy apps always start with window containing partial white background in Windows 11.

[piaoger]

I tried a couple of bevy apps, including examples, in my Windows 11 and found they alway start with (white+black) background. Is there a way to fix it?

OS: windows 11
AdapterInfo { name: "NVIDIA T600 Laptop GPU", vendor: 4318, device: 8122, device_type: DiscreteGpu, backend: Vulkan }

The below sample code for me generates the same problem. I get a white flash, then black solid background.

// main.rs
#![cfg_attr(not(debug_assertions), windows_subsystem = "windows")]

use bevy::{math::vec3, prelude::*};

const PADDLE_START_Y: f32 = 0.0;
const PADDLE_SIZE: Vec2 = Vec2::new(120.0, 20.0);
const PADDLE_COLOR: Color = Color::rgb(0.3, 0.3, 0.7);

fn main() {
    App::new()
        .add_plugins(DefaultPlugins)
        .insert_resource(ClearColor(Color::rgb(0.5, 0.5, 0.9)))
        .add_systems(Startup, setup)
        .add_systems(Update, bevy::window::close_on_esc)
        .run()
}

#[derive(Component)]
struct Paddle;

pub fn setup(mut commands: Commands) {
    // camera
    commands.spawn(Camera2d::default());

    // paddle
    commands.spawn((
        SpriteBundle {
            transform: Transform {
                translation: vec3(0.0, PADDLE_START_Y, 0.0),
                ..default()
            },
            sprite: Sprite {
                color: PADDLE_COLOR,
                custom_size: Some(PADDLE_SIZE),
                ..default()
            },
            ..default()
        },
        Paddle,
    ));
}

If anyone finds this unanswered question, in the window_settings example it is explained why this is the case and how to fix it:

• start with an invisible window
• make it visible after 3 frames

It worked for me.
