Yeah its tearning.
// init
SDL_Init(SDL_INIT_EVERYTHING);
screen = SDL_SetVideoMode(800, 600, 32, SDL_SWSURFACE | SDL_DOUBLEBUF);
// render
SDL_FillRect(screen, NULL, 0);
for(int i=0; i<box_vec.size(); i++)
{
SDL_FillRect(screen, &box_vec->rect, box_vec->color); // problem rect
}
SDL_Flip(screen);
// update
box_vec->rect.x += box_vec->xvel;
box_vec->rect.y += box_vec->yvel;
// init
SDL_Init(SDL_INIT_EVERYTHING);
screen = SDL_SetVideoMode(800, 600, 32, SDL_SWSURFACE | SDL_DOUBLEBUF);
// render
SDL_FillRect(screen, NULL, 0);
for(int i=0; i<box_vec.size(); i++)
{
SDL_FillRect(screen, &box_vec->rect, box_vec->color); // problem rect
}
SDL_Flip(screen);
// update
box_vec->rect.x += box_vec->xvel;
box_vec->rect.y += box_vec->yvel;
You're not calling SDL_Init and SDL_SetVideoMode every frame, are you? Those are a at-initialization-resource-loading things and should not be mixed with realtime code...

No, Init(); is in constructor it run only once, Render(); , Update(); and Fps(); run every frame
