Yep.

Yep. 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.

Not easily, but it is definitely not my imagination. You can't
reproduce the problem at all?
