I’m using SFML to develop a game, and I need to hide the mouse cursor within the game window. However, calling setMouseCursorVisible(false) doesn’t seem to hide the cursor as expected. Here is the code that results in a cursor displayed:

#include <SFML/Graphics.hpp>
#include <iostream>

int main() {
    sf::RenderWindow window(sf::VideoMode(800, 600), "Minimal Example");

    // Attempt to hide the mouse cursor
    window.setMouseCursorVisible(false);

    while (window.isOpen()) {
        sf::Event event;
        while (window.pollEvent(event)) {
            if (event.type == sf::Event::Closed)
                window.close();
        }

        window.clear();
        window.display();
    }

    return 0;
}

I even tried using a transparent cursor:

#include <SFML/Graphics.hpp>
#include <iostream>

int main() {
    sf::RenderWindow window(sf::VideoMode(800, 600), "Custom Cursor Example");

    // Create a transparent image for the cursor
    sf::Image cursorImage;
    cursorImage.create(32, 32, sf::Color::Transparent);
    sf::Cursor cursor;
    
    if (cursor.loadFromPixels(cursorImage.getPixelsPtr(), sf::Vector2u(32, 32), sf::Vector2u(0, 0))) {
        window.setMouseCursor(cursor);
    } else {
        std::cerr << "Failed to load custom cursor" << std::endl;
    }

    while (window.isOpen()) {
        sf::Event event;
        while (window.pollEvent(event)) {
            if (event.type == sf::Event::Closed)
                window.close();
        }

        window.clear();
        window.display();
    }

    return 0;
}

But when I do this it just default back to the default cursor. If I do

cursorImage.create(32, 32, sf::Color::Red);

instead, the cursor becomes a red square.
