Slashcash, would you mind checking if it fixes it for you? https://github.com/dabbertorres/SFML/tree/unix-window-fullscreen

I can confirm this fixes the issue here too!

Window / Setting window visibility off/on causes strange (?) behaviour on Linux

« on: January 06, 2018, 01:22:28 pm »

Setting the visibility off and then back on for a fullscreen window causes a strange behaviour: just before setting the visibility off (with setVisible) the fullscreen window is shiny and glorious. When i set it off and then back on again when i need it the window is shown again but with a titlebar and not in a fullscreen mode.

Is this the intended behaviour? Am i doing something wrong? I'm trying to achieve an unrealistic thing? Any workaround on this?
It is happening on my Kubuntu box with KDE

this is a minimal snippet of compilable code that reproduces the problem

#include <SFML/Graphics.hpp>

int main()
{
    sf::RenderWindow window(sf::VideoMode(1920, 1080), "SFML works!", sf::Style::Fullscreen);
    sf::CircleShape shape(100.f);
    shape.setFillColor(sf::Color::Green);

    while (window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::KeyPressed && event.key.code == sf::Keyboard::Escape) window.close();
            if (event.type == sf::Event::KeyPressed && event.key.code == sf::Keyboard::A) { window.setVisible(false); window.setVisible(true); }
        }

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

    return 0;
}
 

Just before changing the visibility of the window:


Right after (please note the titlebar and the task bar showing)



I'm not even sure if it is SFML's fault or if it's KDE messing things up and i'm unable to test it on other machines at the moment.
