[Message part 1 (text/plain, inline)]

When using an RTL language in visual-line-mode + org-mode, a sec
ond dispalyed-line of typing for a paragraph appears ABOVE the prior
dispalyed-line. In other words, the rendering for paragraphs is in
reverse-line order. This does not affect paragraph sequence within a
document, only dispalyed-line sequence within a single paragraph.

This is by design, and can only be fixed by a radical change in the
Emacs display engine and how the bidirectional text is rendered by it
(the reordering needs to be done _after_ a line of text is rendered
for display).

As a workaround, either use hard newlines, to make your lines shorter
than the window width, or set bidi-paragraph-direction in that buffer
to right-to-left (or nil, if some of the paragraphs in that Org buffer
use a predominantly LTR script).
