Fullscreen on 0.99.0+ in Windows10

[ScottWill]

In version 0.98.0 the following will create a fullscreen window on my Win10 machine. Starting with 0.99.0 continuing to 0.105.0 the same code will not go into fullscreen for me in either stable or nightly on Win10. It will go fullscreen for all piston_window versions in an Ubuntu 18.04 LTS VM on the same machine.

[dependencies]
piston_window = "0.105.0"

extern crate piston_window;
use piston_window::*;

fn main() {
    
    let mut window: PistonWindow = WindowSettings::new("fullscreen test", (640, 480))
        .exit_on_esc(true)
        .fullscreen(true)
        .build()
        .unwrap_or_else(|e| { panic!("Failed to build PistonWindow: {}", e) });
        
    while let Some(e) = window.next() {
        window.draw_2d(&e, |_, g, _| {
            clear([0.5, 1.0, 0.5, 1.0], g);
        });
    }

}

not sure what info would be relevant, can provide more on request.

• Windows 10 Pro 64-bit
• NVIDIA GeForce GTX 1080

Same problem.

On win10, the "fullscreen window" is displayed on top-left of the screen with still the original size, but in Ubuntu, it will still be a moveable window. Both OS meet problem with fullscreen.
