`_sdl2.video.Window(maximized=True)` not starting in fullscreen in Hyprland + Arch Linux

Environment:

pygame-ce 2.5.1 (SDL 2.30.6, Python 3.12.5)
Platform:               Linux-6.10.8-arch1-1-x86_64-with-glibc2.40

Current behavior:
This is the code that works on other platforms, but not on Hyprland

import pygame
import pygame._sdl2.video

pygame.init()
win = pygame._sdl2.video.Window(resizable=True, maximized=True)
screen = win.get_surface()
pygame.print_debug_info()
clock = pygame.Clock()
while True:
    events = pygame.event.get()
    for event in events:
        if event.type == pygame.QUIT:
            raise SystemExit
    win.flip()

Expected behavior:
It was supposed to start the window in fullscreen, but instead its a tiny window
It works with the regular display API and pygame.FULLSCREEN flag

import pygame

pygame.init()
win = pygame.display.set_mode((500, 500), pygame.FULLSCREEN)
clock = pygame.Clock()
while True:
    events = pygame.event.get()
    for event in events:
        if event.type == pygame.QUIT:
            raise SystemExit
    win.fill("black")
    pygame.display.flip()

Steps to reproduce:

1. Just run the snippet on Arch+Hyprland

Test code

import pygame
import pygame._sdl2.video

pygame.init()
win = pygame._sdl2.video.Window(resizable=True, maximized=True)
screen = win.get_surface()
pygame.print_debug_info()
clock = pygame.Clock()
while True:
    events = pygame.event.get()
    for event in events:
        if event.type == pygame.QUIT:
            raise SystemExit
    win.flip()

Maximized is not fullscreen. It just means the window is supposed to be the size of the window. There are fullscreen and fullscreen_desktop kwargs to choose and use. Reference docs in case you haven't seen it on the site: https://pyga.me/docs/ref/window.html

I'd be also interested to know what happens if you add a KEYDOWN -> win.maximize() call. Maybe it can't start maximized but could be maximized after creation on your platform.

Also we've just promoted pygame.Window to public API in 2.5.2.dev2, so please try with that. pygame._sdl2.video.Window is basically an old alias at this point.

Works as expected on Windows.

Worked as expected on arch + kde as well. This issue was caught using an old project of mine; I'll be swapping the alias shortly. The "maximised" behaviour is what I was after, specifically not full screen. At least not until I'm a lot further along in development and don't have to close the window so often. On hyprland it stays shrunk to whatever size is passed as.
