I suspect the problem happens when the cursor moves to the modeline. When
you do the page-up and page-down, at some point you will notice the cursor
on the mode line. After that, you will see the minibuffer height increase
and the garbling starts.

To me, it appears like the count of lines/rows in the frame during the
scrolling is off by 1. This has a domino effect on subsequent page up and
down and ends up messing the modeline and the menubar.

Well, this is just a hypothesis based on observation.
