> To reproduce: Start Emacs (without any customization). Open any (larger) file. Scrolling down as long as possible by using the mouse wheel stops only when the last line of the buffer becomes the first visible line of its frame, so that the rest of the frame becomes empty. This is rather unaesthetic. Also, it is inconsistent with scrolling down by using the down-arrow key, which, as in other applications, stops already when the buffer still occupies almost all of its frame.

This is a feature.  (Other applications behave like that, and there
were enough Emacs users who wanted a similar behavior in Emacs.)  If
you don't like this behavior, customize the variable
scroll-bar-adjust-thumb-portion to the nil value.

To reproduce: Start Emacs (without any customization). Open any (larger) =
file. Scrolling down as long as possible by using the mouse wheel stops =
only when the last line of the buffer becomes the first visible line of =
its frame, so that the rest of the frame becomes empty. This is rather =
unaesthetic. Also, it is inconsistent with scrolling down by using the =
down-arrow key, which, as in other applications, stops already when the =
buffer still occupies almost all of its frame.
