Thanks for the answer

¿Should I add a new track issue on github for this problem?

I hope there is a solution, somehow...

Graphics / Re: sf::RenderTexture bug when destroyed in fullscreen

Try it today on another computer (win 7 32 bits, nvidia 8600GT) and the result is the same "black blink" effect when Rendertexture is destroyed.

In windowed mode all run fine, smooth, without any flickering. But in fullscreen, everytime I destroy a rendertexture, or a entity that stores a rendertexture, because I don't gonna use it anymore, the flicker appears.

Try it with Vsynch enabled and same result.

¿Anyone with nvidia cards (or ati) can confirm this?

PS: I use Visual Studio 2010.

Graphics / sf::RenderTexture bug when destroyed in fullscreen

« on: July 21, 2013, 08:24:40 pm »

Greetings everyone.

I have integrated SFML in my project development that uses some RenderTextues, Sprites,... and when try it t run in fullscreen, the entity that stores the RenderTexture is destroyed, cause some sort of flickering in the screen.

For 1-2 frames, the screen goes black and then return to normal. Trying to reproduce this problem, I've discovered what causes this comportament but not why.

In the following code, I find that when a RenderTexture is destroyed (out of scope/delete), the problem appears.

My specs are Win 7 64 bits, Nvidia 560Ti (driver version 320.49 WHQL), i5 2500k.

#include <iostream>
#include <SFML\Graphics.hpp>
#include <SFML\Window.hpp>


int main()
{
    sf::RenderWindow App(sf::VideoMode(640, 480, 32), "SFML Test", sf::Style::Fullscreen);
        App.setFramerateLimit(60);

        sf::RectangleShape rect(sf::Vector2f(300,300));
        rect.setFillColor(sf::Color::White);
        rect.setPosition(170, 100);
       
        sf::RenderTexture *tex_ptr = NULL;
       
        while (App.isOpen())
        {
                sf::Event Event;

                while (App.pollEvent(Event))
        {
            // Close Window
            if (Event.type == sf::Event::Closed)
                return 1;

                        if (Event.type == sf::Event::KeyPressed)
                        {
                                // Exit
                                if (Event.key.code == sf::Keyboard::Escape)
                                        return 1;      

                                // Each time F1 is pressed, screen goes black in some sort flickering
                                if (Event.key.code == sf::Keyboard::F1)
                                {  
                                        sf::RenderTexture tex;
                                        tex.create(200,200);
                                }

                                // Each time F2 is pressed, screen goes black in some sort flickering
                                if (Event.key.code == sf::Keyboard::F2)
                                {  
                                        tex_ptr = new sf::RenderTexture();
                                        tex_ptr->create(200,200);
                                        delete tex_ptr; // if this line is commented, does not flick
                                }
                        }
                }

                App.clear();
                App.draw(rect);
                App.display();
        }

    return 0;
}
