Maybe I am not finding the right words… The text cursor travels through every visible line of text, for example hitting the columns 12, 59, 107, … also these positions all belong to one long line of broken text. There is also no fixed rule by which the column number increases (or decreases when going towards the top of the buffer). This is really disturbing, I instantly assumed column-number-mode was broken.

You'd have to rethink that when you use visual-line-mode, those are
features, not bugs.  (Why do you care about how columns
increase/decrease?  For that matter, why do you turn on
column-number-mode at all?)

I have no problem with this when I try it now.  Does it happen for you
in "emacs -Q", if you just turn on visual-line-mode?

> And there also lines segments containing the last part of a broken line that cannot be reached at all, neither with the mouse nor by using the cursor movement keys… 

Are you again talking about putting the cursor beyond the text?
That's impossible in Emacs.

If you are talking about something else, please elaborate.

I cannot reproduce this.  Can you give a recipe?
