sf::RenderTexture Flipped

[Mina66]

Hello!
Raised two questions on the same topic

Here is the code

#include <SFML/Graphics.hpp>

int main()
{
    sf::VideoMode VMode(800, 600, 32);
    sf::RenderWindow Window(VMode, "SFML 2", sf::Style::Close);


    sf::RenderTexture texture;
    if (!texture.create(500, 500))
     return -1;

    sf::Text text;
    text.setString("TEST");
    text.setPosition(0.0f, 0.0f);
    text.setColor(sf::Color(255, 0, 0));

    sf::Texture texture_img;
    texture_img.loadFromFile("image.png");
    sf::Sprite sprite_image;
    sprite_image.setTexture(texture_img);

    while(Window.isOpen())
    {
        sf::Event Event;
        while(Window.pollEvent(Event))
        {
            switch(Event.type)
            {
                case sf::Event::Closed:
                    Window.close();
                    break;
                case sf::Event::KeyPressed:
                    if(sf::Keyboard::isKeyPressed(sf::Keyboard::Escape))
                        Window.close();
                    break;
                default:
                    break;
            }
        }

        texture.clear(sf::Color::Blue);
        texture.draw(text);
        texture.draw(sprite_image);
//        texture.display();

        Window.clear(sf::Color(128, 128, 128));

        sf::Sprite sprite(texture.getTexture());
        Window.draw(sprite);
        Window.display();
    }
    return 0;
}

1. Why texture turns upside down, and what you can do

2. When the string / / texture.display (); longer displayed texture that I do not?

More information about the upside down RenderTexture.
Anyway, your RenderTexture has to call display after you draw something on it. The sf::RenderTexture documentation states that "Not calling it [display] may leave the texture in an undefined state", upside down for example. 

I don't understand question number 2.

I don't understand question number 2.

Uncomment this line if nothing is drawn

Looked at the forum here that I found.

        sf::Sprite sprite(texture.getTexture());
        sprite.setScale(1.0, -1.0);
        sprite.setPosition(0.0, 500.0);

But then the wrong position on the Y.
Is that correct?

Try to run on another computer, worked. What's the matter do not know, maybe in a video card.

Here is another way to work on both computers.

        Window.clear(sf::Color(128, 128, 128));
        sf::Texture tex(texture.getTexture());
        sf::Sprite sprite(tex);
        Window.draw(sprite);
        Window.display();

Did you actually read what G. said?

And your second question is still kind of lost in translation or something like that...
