Bug

If you use the code below, when we draw Quad with Mesh and then draw other sprite in the same Z-coordinate the result is uncertain

let pentagon = Quad::new(Vec2 { x: 100., y: 100.});
let handle = meshes.add(Mesh::from(pentagon));
commands.spawn(ColorMesh2dBundle {
        mesh: handle.into(),
        transform: Transform::from_translation(Vec3::new(0., 0., 1.)),
        ..default()
    });

commands.spawn(SpriteBundle {
        sprite: Sprite {
            color: Color::rgb(0.25, 0.25, 0.75),
            custom_size: Some(Vec2::new(150.0, 100.0)),
            ..default()
        },
        transform: Transform::from_translation(Vec3::new(0., 0., 1.)),
        ..default()
    });

Sometimes it only shows blue rectangle, sometimes it shows purple and blue rectangles. You can try to build more and more times.
