I want Emacs to scroll on [up] and [down] cursor keys one line at a time.
I have already installed and checked out following packages:
Only smooth-scrolling works, but while scrolling down it starts sometimes to jump instead of scrolling by one line.
Is it possible to have a bug-free smooth scrolling one line at a time in Emacs?
P.S. I can't reliably reproduce the problem with the jumps by multiple lines. It occurs preferably in windows with a small number of lines, but sometimes it works OK when only three lines are visible.
Sometimes the position of the point (cursor) changes up and down and this seem to depend on the length of the line and occurs preferably near very long lines (for example 250 chars). This behavior appears to be reproducible, so you can check it out yourself if you are using the smooth-scrolling package.
