It's not a bug, it's how the display engine was designed to work.  If
we decide to change the design, and stop extending the face of the
last character to the edge of the window, when the face covers the
newline, then the issue with display-fill-column-indicator-mode in Org
mode will also go away.  But we haven't yet made such a decision, see
the discussion which starts here:
