Firstly i create a sf::Renderwindow, i turn on PreserverOpenGlStates then i use function specified by myself - InitGL(),then i create sf::String and try do draw it after cleaering the window(using gl functio, because window->clear() doesnt work), it doesnt show. If i draw any texture using OGL and then try to write a text, all screen texture colors change to the text's color bu the text doesnt show...
wtf?
