It's hard to fix because I don't see this error on my computer. I tried something, can you tell me if the new code solves the problem?

The new API is looking promising! Congrats! However I'm really going to miss that sf::Sprite::GetSize().. oh well that's life! Looks like your long term planning might be paying off on this :D

No error message on the shader example but the window just opens and closes now

Strange. Would you mind running the debugger, and show me the call stack?

Hum. You probably did something wrong. Try to delete everything, download SFML again and compile it directly in debug mode.

Anything I draw onto a RenderTexture isn't displayed.

Code: [Select]
   sf::RenderTexture texture;
    if (!texture.Create(300, 300)) return -1;

    sf::CircleShape circle(100);
    circle.SetFillColor(sf::Color::Green);

    texture.Clear(sf::Color::Blue);
    texture.Draw(circle);
    texture.Display(); // display the drawn circle

    while (window.IsOpened()){
        window.Clear();
        sf::Sprite sprite(texture.GetTexture());
        window.Draw(sprite);
        window.Display();
    }


Output: black screen with a blue square on top left; the green circle is missing.


Also, possibly a typo on documentation?
sf::RenderTexture::SetSmooth: This parameter is enabled by default.
sf::Texture::SetSmooth: The smooth filter is disabled by default.

Would you mind providing a complete source code? I know that it's almost complete, but this evening I'm a little lazy and don't have much time ;)

It's really just that :P

Code: [Select]
#include <SFML/Graphics.hpp>

int main(){

    sf::RenderWindow window(sf::VideoMode(800, 600), "SFML window");

    sf::RenderTexture texture;
    if (!texture.Create(300, 300)) return EXIT_FAILURE;

    sf::CircleShape circle(100);
    circle.SetFillColor(sf::Color::Green);

    texture.Clear(sf::Color::Blue);
    texture.Draw(circle);
    texture.Display();

    sf::Event event;
    while (window.IsOpened()){
        while (window.PollEvent(event)){
            if (event.Type == sf::Event::Closed){
                window.Close();
            }
        }
        window.Clear();
        sf::Sprite sprite(texture.GetTexture());
        window.Draw(sprite);
        //window.Draw(circle);
        window.Display();
    }
    return EXIT_SUCCESS;
}

It works for me. Do you have an Intel integrated graphics chipset?

Are your drivers up-to-date?

After trying a lot seems that I couldn't get new drivers for my graphics card.. my guess is either due to ATI acquisition by AMD or this card being too old (5 years or so). It's not a bad time to think on a new computer.
