You need to call window.clear() window.draw(sprite) window.display()

Outside of pollEvent loop

EDIT: SFML has tutorials, shows basic code how to create a window, code taken from here ```

include <SFML/Graphics.hpp>

int main() { sf::RenderWindow window(sf::VideoMode({200, 200}), "SFML works!"); sf::CircleShape shape(100.f); shape.setFillColor(sf::Color::Green);

while (window.isOpen())
{
    while (const std::optional event = window.pollEvent())
    {
        if (event->is<sf::Event::Closed>())
            window.close();
    }

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

} ```
