Title: Duplicate windows on macOS (15.2) using SFML 2.6.2
Post by: Oliver Ewald on December 18, 2024, 07:58:06 pm

I am using SFML (2.6.2) for macOS (15.2) on Xcode.
I face the problem that in ca. 8 out of 10 cases I get a duplicate (highly overlapping) window displayed.
I reduced my code to the below minimal code example that produces the problem:

#include <SFML/Graphics.hpp>
int main() {
    sf::RenderWindow window(sf::VideoMode(800, 600), "SFML Test");
    while (window.isOpen()) {
        sf::Event event;
        while (window.pollEvent(event)) {
            if (event.type == sf::Event::Closed)
                window.close();
        }
        window.clear(sf::Color::Black);
        window.display();
    }
    return 0;
}

Can anyone help me to solve that problem?

Do you have a screenshot? I don't quite understand what "duplicate (highly overlapping)" means exactly.

When does this happen? At the start of the application? Do you start it multiple times?

I got it working with a "sleep(0.2)" statement directly before the RenderWindow statement:

[...]
sleep(0.2);
RenderWindow window(VideoMode(504, 504), "The game of chess");
[...]
