If I use Page Up or Page Down to move while composing a new message, only the top (or bottom) line is refreshed during scrolling; the rest of the message remains static until the cursor reaches its new position.  This is not the case when scrubbing with the scrollbar or moving with the arrow keys; in both of those cases, scrolling is smooth.
