hmm, well upgrading to 2.0 may be the first step towards resolving this

I want to use a stable version of SFML.

[...], BUT, you should use a rendertexture instead of capture() to do this sort of thing. [...]

I use the current version of SFML (1.6). sf::RenderTexture::capture() does only exist in 2.0.
Calling "display()" before "capture()" did not help, but now the background is black instead of white.

I can see the right background for a very short moment on startup.

 for(unsigned int y=0; y < mCity->getGridSize().y; ++y)
            {
                cell.setFillColor(sf::Color::Red); break;
                cell.setPosition(x*scale, y*scale);
                mWindow->draw(cell);
            }

Shouldn't that break be conditional?

Well... it should not be there ;-)
I cleaned up the code before i posted it here and forgot this litte "break".
Original code:

                switch(grid[x + mCity->getGridSize().x * y])
                {
                    case(City::GridCellType::Free): cell.setFillColor(sf::Color::White); break;
                    case(City::GridCellType::PublicPlace): cell.setFillColor(sf::Color::Green); break;
                    case(City::GridCellType::PoliceStation): cell.setFillColor(sf::Color::Blue); break;
                    case(City::GridCellType::Building): cell.setFillColor(sf::Color::Black); break;
                    default: cell.setFillColor(sf::Color::Red); break;
                }

Problem: When mCity->getEntities is > 1 or mWindow->draw() is called twice the background is just white.
What the code does: It renders a grid once into gridSprite. Then every time gridSprite is drawed, after that some circles are drawed on this.
Code:

void CityGridViewer::paintCity()
{  
    // 1. Render grid if necessary
    static bool targetReady=false;
    static sf::Texture gridTex;
    static sf::Sprite gridSprite;

    if (!targetReady)
    {
        sf::RectangleShape cell;
        cell.setSize(sf::Vector2f(5,5));
        cell.setOutlineColor(sf::Color::Black);
        cell.setOutlineThickness(1);
        City::GridCellType const*const grid = mCity->getCityGrid(); // it returns a copy of the grid
        for(unsigned int x=0; x < mCity->getGridSize().x; ++x)
            for(unsigned int y=0; y < mCity->getGridSize().y; ++y)
            {
                cell.setFillColor(sf::Color::Red);
                cell.setPosition(x*scale, y*scale);
                mWindow->draw(cell);
            }

        sf::Image gridImage = mWindow->capture();
        gridTex.loadFromImage(gridImage);
        gridSprite.setTexture(gridTex);
        targetReady=true;
    }
    mWindow->draw( gridSprite );

    // 2. Render entities
    sf::CircleShape entity;
    entity.setFillColor(sf::Color::Red);
    entity.setRadius( 5 );
    for (auto& e : mCity->getEntities())
    {
        entity.setPosition( e.position.x, e.position.y );
        mWindow->draw(entity);
    }
}

Does anyone has an idea?
Additionally, i'm using win7 x64 and compile with msvc11 x86. I tested it on a x64 linux with gcc4.7 x64 and it worked...
