Title bar display and closing problem

[Jeanjean Lesage]

Hello, I'm a beginner in C++ and SFML for game creation under linux(Pop!_OS 22.04 LTS). I tested the code on the official SFML website, everything seems to work but the title bar doesn't display; it's the same with other codes. I need your help, please. Here is an example of a code I tested:

#include
#include
#include
#include
#include

int main()
{
sf::RenderWindow window(sf::VideoMode(640, 480), "SFML works!", sf::Style::Titlebar);
sf::Event ev;

while(window.isOpen()){
    
    while(window.pollEvent(ev)){

        switch(ev.type){
            case sf::Event::Closed:
                window.close();
                break;
            case sf::Event::KeyPressed:
                if(ev.key.code == sf::Keyboard::Escape){
                    window.close();
                    break;
                }
            default:
                break;
        }
         
    }

    //Render
    window.clear(sf::Color::Blue);
    window.display();
}

return 0;

}

Your question is about SFML rather than C++. You are more likely to get an answer at SFML[^]

Ok. I'll post it in SFML forum.
