This happens even if the window is made slightly smaller

Not fixed with #15988

[BenjaminBrienen]

I think the Camera Viewport needs to be updated when the window is resized.

[BenjaminBrienen]

Spawning the Camera2d with a Transform bundle instead allows resizing to work.

    commands.spawn((
        Camera2d,
        Transform::from_xyz(0., 0., 0.).looking_at(Vec3::ZERO, Vec3::Y),
    ));
