One thing I would question is that there's no SDL_RenderClear().  The docs say "You are strongly encouraged to call SDL_RenderClear() to initialize the backbuffer before starting each new frame's drawing".  Does it make any difference if you change it as follows:

		SDL_SetRenderTarget(renderer, NULL);
		SDL_SetRenderDrawColor(renderer, 0, 0, 0, 255);
		SDL_RenderCopy(renderer, texture3, NULL, NULL);
