Enabling visual-line-mode and adding line-prefix and wrap-prefix properties to a long paragraph of text produces erratic navigational behaviour.
To reproduce:
1. $ emacs -Q
2. insert a long paragraph of text
M-: (url-insert-file-contents "https://gist.githubusercontent.com/rnkn/d5987c3495901e4950782f6648846e4e/raw/c22074e8f0940f6ec9c8b729f04567dc50664823/loren-ipsum.txt")
3. turn on visual line mode
M-: (visual-line-mode 1)
4. add text properties
M-: (add-text-properties (point-min) (point-max) '(line-prefix (space :align-to 10) wrap-prefix (space :align-to 10)))
5. C-n past window height.
Expected results:
Navigation should continue by visual line.
Actual results:
Navigational behaviour becomes erratic. Point will no long move with visual lines, instead jumping to different columns. This is more pronounced with a window 80 columns or less.
Configuration:
GNU Emacs 24.5.1 (x86_64-apple-darwin15.5.0, NS apple-appkit-1404.47) of 2016-06-26
Configured using:

--infodir=/usr/local/Cellar/emacs/24.5/share/info/emacs
--prefix=/usr/local/Cellar/emacs/24.5 --with-xml2 --without-dbus
--without-gnutls --with-ns --disable-ns-self-contained'

Point will no long move with visual lines, instead jumping to different columns. This is more pronounced with a window 80 columns or less. Initial investigation indicates that this is a very old problem: I see it in Emacs 23.1, which is when visual-line-mode was introduced. ^ permalink raw reply [flat|nested] 6+ messages in thread

Indeed, a very old bug, now fixed on the master branch. Thanks. ^ permalink raw reply [flat|nested] 6+ messages in thread

It's easy for people closing bugs to include the version information when they do so, in a way that debbugs can pick up. (But whether Emacs sticks to that release schedule is another matter.) ^ permalink raw reply [flat|nested] 6+ messages in thread
