This is a feature: scrolling (and redisplay in general) in the mini-window is tailored to try and display the most important part of the minibuffer text. The feature is intended to support various minibuffer-editing packages which display a lot of text in the mini-window when the user is prompted for a file name or other similar stuff, of which there are a lot of possible candidates. If you set the variable redisplay-adhoc-scroll-in-resize-mini-windows to a nil value, you will get the "normal" scrolling behavior in the mini-window.

I tried to use this recipe, but it produces weird results, and I don't see what you describe. Would you like to show an easier to understand recipe, or describe what should be in the min-window as result of the recipe? And what exactly are your expectations from C-v/M-v in this case? I tried this: M-x C-u 99 C-q C-j M-< after that, C-v scrolls the mini-window as expected, so that I get to the end in 13 C-v keypresses. Which looks reasonable to me. > Also, if you now repeatedly M-v, the buffer will just scroll up and > down three lines.

M-v in the minibuffer is bound to switch-to-completions, so I'm unsure what you expected here. Adding Juri who worked on the scrolling commands in the minibuffer.
