If you want *good* and 100% guaranteed unflickered animation you SHOULD bypass system GUI drawing. This means using OpenGL/DirectX.
OpenGL is more portable way and it is supported by U++.
In addition to Mindtraveller advice, in Example/SDLExample and in Bazaar/SDLCtrl_demo you have nice examples of softly scrolling texts even with effects.
