gnus-summary-scroll-up scrolls one page instead of one line

gnus-summary-scroll-up scrolls one page instead of one line

[Tassilo Horn]

Hi all,

since a few days my CVS Gnus has some scrolling problems. If I view an
article by hitting RET (`gnus-summary-scroll-up') on it in *Summary*, I
get the following behavior:

  - as long as there are visible headers (Subject, From, etc.) on top of
    the buffer, pressing RET scrolls exactly one line as it should be.

  - when the last visible header scrolled out of the visible buffer part
    pressing ret results in scrolling one entire page like SPACE
    (`gnus-summary-next-page') does.

How can I get back to the old behavior, e.g. RET always scrolls only one
line?

Bye and thanks,
Tassilo

Could you try to identify the responsible change (using the -D
argument of cvs)?

Anyhow, if the problem is only in the CVS version, you'd better ask on
the ding list.

Sure, but it seems not be be Gnus' fault. I'm sure that I have these
scrolling issues for about one or two weeks, but even the version you
get with `cvs up -D 2006-08-01' suffers from the same problem.

So it seems I have to do the same with my emacs checkout. Could you name
the files in emacs which could cause the issue, so that I have a clue to
when I should downgrade? (It's building about 25 minutes, so try and
error is to costly...)

Sorry, I don't see any obvious changes in src/ChangeLog and
lisp/ChangeLog.  Please report it on emacs-devel or emacs-pretest-bugs
(M-x report-emacs-bug RET).  Preferably, try to reproduce the problem
with the bundled Gnus version (5.11).  Be sure to do this on a
different account or HOME directory, because downgrading Gnus may lead
to problems.

FWIW, I can't reproduce the problem, neither with my usual settings
nor with a very minimal setup (neither with No Gnus nor 5.11).

Bye, Reiner.

I tried it on my test account, and all worked fine. But I was able to
locate the source of the problem. Fasten your seat belts -- one
customized face is causing the trouble!

--8<---------------cut here---------------start------------->8---
(custom-set-faces
 '(mode-line ((((class color) (min-colors 88)) (:background "darkred" :foreground "grey" :box (:line-width 1 :style released-button) :height 0.8 :family "helvetica")))))
--8<---------------cut here---------------end--------------->8---

If I commend out this line, scrolling works as it should. With this line
I can reproduce the bug in both No Gnus and 5-11.

Could you try to reproduce it with my `custom-set-faces'?

I'm going to report the bug via `report-emacs-bug' anyways.

Bye and thanks,

A proportional font for `mode-line' has been suggested recently in
some newsgroup or list.  Have you changed the face `mode-line'
recently, i.e. there's probably no recent relevant change in Emacs or
Gnus?

":line-width 1" seems to be the culprit (the default is -1, see
`faces.el').

(set-face-attribute 'mode-line nil
		    :box '(:line-width 1 :style released-button))

You may Cc ding (it's possible that the bug is in Gnus).

Bye, Reiner.

Yep, that was Kim Storm's answer
(<mailman.7811.1160142023.9609.help-gnu-emacs@gnu.org>) to my question
on gnu.emacs.help.

Yes.

I can confirm this. Changing the box width to -1 fixes the problem.

Sorry, too late. The message still waits for approval on the pretest
mailing list.

Ok, the bug report has hit gmane.emacs.devel:
<E1Gcn4s-0006RB-Ct@fencepost.gnu.org>
