You asked why Org does not use default. That was the reason.

Unfortunately, the original test file is not available anymore, so we
cannot easily test if the slowdown is still there.

I tried to create a large file in Persian, but I cannot see any
difference in performance when bidi-paragraph-direction is nil or
'left-to-right. However, I was able to see a difference using the
attached file when moving through an artificially created very long line
in the second heading. In my testing, setting bidi-paragraph-direction
to nil *improves* the performance.

So, my datapoint indicates that changing bidi-paragraph-direction back
to nil could make sense. However, I am not using right-to-left text
daily in my system. Testing from people who do use right-to-left
languages would be appreciated.

Best,
Ihor
