Subject: Weird article scrolling in Gnus with customized face
X-Spam-Status: No, score=0.1 required=5.0 tests=FORGED_RCVD_HELO
autolearn=failed version=3.0.4
Ok, I start up Gnus. Now, 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.
- the same applies to M-RET
I tried it on a test account, and all worked fine. But I was able to
locate the source of the problem: One customized face is causing the
trouble!
(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")))))
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.

The problem could be that the last line is only partially visible, and
we have a complex/messy piece of code to handle this in the redisplay
code by recenting point.
If that is the case, I would DEFINITELY NOT try to fix this before the
release, at the risk of making even bigger problems in other cases.

Hi all,
I could isolate the problem even better:

^^^^^^^^^^^^^
If I set :line-width to -1 (the default value), scrolling works as
expected.
>> "helvetica")))))

The problem could be that the last line is only partially visible, and
we have a complex/messy piece of code to handle this in the redisplay
code by recenting point.
It sounds plausible.
How about if you look for some obvious straightforward bug,
and if you find one and you see a safe fix, install that.
Otherwise add a comment saying "fixme" with a description of
the case that fails.

I don't have time to debug it now.

Can't we just remember the bug and work on it after the release...

Memory is not so reliable -- would you please add a "fixme" comment
with a description of the test case, or a reference to the message?
That will help us remember.
