One thing to note is that make sure you are clipping properly all the
drawing you do. However it sounds like there are some other bugs in the
application. Try to run it in desktop environment using valgrind
(http://valgrind.org/). Also from the optimization point of view, make
sure you are converting all your surfaces to same format as screen has
(using SDL_ConvertSurface for example).
