After inserting about 7000 lines into the *shell* buffer, as described, press and hold down M-v (or PageUp) for several seconds. Redisplay freezes, not updating until about two seconds after the key is released. Then it updates the screen with the new cursor position. But if bidi-paragraph-direction is set to 'left-to-right, the display updates in real time as I press and hold M-v. > Can you quantify it?
