Comment 1 Martin Gerhardy 2011-11-12 06:53:40 UTC 
this is the code part i used to create the window
	[...]
	if (!SDL_WasInit(SDL_INIT_VIDEO)) {
		if (SDL_Init(SDL_INIT_VIDEO) == -1) {
			return -1;
		}
	}

	int flags = SDL_WINDOW_OPENGL | SDL_WINDOW_SHOWN | SDL_WINDOW_RESIZABLE;

	if (fullscreen)
		flags |= SDL_WINDOW_FULLSCREEN;

	SDL_GL_SetAttribute(SDL_GL_MULTISAMPLEBUFFERS, 1);
	SDL_GL_SetAttribute(SDL_GL_MULTISAMPLESAMPLES, 4);
	SDL_GL_SetAttribute(SDL_GL_DOUBLEBUFFER, 1);
	SDL_GL_SetAttribute(SDL_GL_DEPTH_SIZE, 24);
	SDL_GL_SetAttribute(SDL_GL_RED_SIZE, 8);
	SDL_GL_SetAttribute(SDL_GL_GREEN_SIZE, 8);
	SDL_GL_SetAttribute(SDL_GL_BLUE_SIZE, 8);
	SDL_GL_SetAttribute(SDL_GL_ALPHA_SIZE, 8);

	_window = SDL_CreateWindow(FULLNAME, SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED, width, height, flags);
