Confirmed and I think I know what happens: DDFSTOP was modified ($d0 to $b8) after position $b8 had passed (but before $d0) causing next line of bitplane to start at first possible hpos ($18) because internal ddfstop matched bit was not set.

OCS Agnus sets this internal bitplane state flag at the end (or start) automatically.

(Not yet sure why it does not work in WinUAE, this should have been handled correctly)

EDIT: Thanks for nice test case
