I have created a bitmap called bmp which is SCREEN_W * 3 and 30 large. I
printed text on it and tried to scroll it using stretch_blit.
It works fine but when the bitmap has scrolled one time the bitmap bmp goes
up one pixel and there is one row with coloured garbage under it and with
every new scroll another line appears!

Help me:
please mail me at
