More information was requested, but no response was given within a
month, so I'm closing this bug report.  If the problem still exists,
please respond to this email and we'll reopen the bug report.

What are the problems you see in this recipe?  Please be specific,
because it could be that what you see on your system we cannot see on
ours.

Also, please show all the information about your build collected by
report-emacs-bug, it could be important while investigating this
issue.

> Increase or decrease text-scale to make this behaviour appear/

If you see problems when you change the text scale, it's because the
screen line's width isn't an integral multiple of the character width.
That's normal and isn't a bug (not one we'd like to fix, anyway).

* Reproducing
- Case 1:
   emacs -Q
   C-u 999 a
   visual-line-mode
   C-p C-a
   C-e C-a

* Notes
Most likely C-a won't move cursor in given scenario and C-e do C-n in
effect. No bug with emacs -nw.

For smaller line C-e can sometimes move cursor before last displayed
character on line. This works with emacs -nw
Increase or decrease text-scale to make this behaviour appear/
