Subject: 23.3; next-line when global-visual-line, highlight-parentheses and
	global-hl-line are active
Date: Fri, 12 Aug 2011 17:37:44 +0200

--text follows this line--
* start emacs -Q
* M-x global-visual-line-mode
* M-x global-hl-line-mode
* M-x load-file <RET> /path/to/highlight-parentheses.el
(highlight-parentheses.el is here:
* M-x set-variable <RET> scroll-step <RET> 1

* create a file that has a very long line that has to be wrapped and add
  many short lines thereafter, such that the whole file won't fit into
  one window

* move point to beginning of document and keep scrolling down by holding
  C-n

At a certain point, the point will just cycle from the bottom of the
window to the middle of the window. This point is reached when the long,
wrapped line has some part that is not displayed anymore and some part
that is displayed anymore. I.e. like follows:

+--------------------------------------+
|...this is the last stuff of the long,|
| wrapped line. the points indicate    |
|that it had a beginning that is not   |
|displayed anymore.                    |
|short line                            |
|short line                            |
|short line                            |
+--------------------------------------+

If the point reaches the bottom line and you try C-n, it jumps to the
middle of the window.

I cannot reproduce this.

You didn't say where did you get highlight-parentheses.el from,
exactly.  (I used some version I found on the net.)  For full
reproducibility, please also attach the precise file you used in your
recipe.

Thanks.

More information was requested, but none was given within 8 years, so
I'm closing this bug.  If this is still an issue, please reopen the bug
report.
