That happened to me before, and it seems to be a result of calling
FIND_PIXEL without switching to page 4. To do so, put:
ld a,4
out (5),a
before FIND_PIXEL is called. Preferrably, but it in an
initialization area (like at the top) that is only called once, not
millions of times.
(BTW, you might want to check other program source code. That port
might be wrong, although I doubt it.)
