Description HansPL 2011-08-02 03:15:41 UTC
Created attachment 49819 [details]
A simple test case.

Another old inheritance from OOo https://openoffice.org/bugzilla/show_bug.cgi?id=115997 ...

In Writer,  when I use paragraph background color AND some spacing below
paragraph AND a wide border,  the background color extends too far above the
paragraph and may even overlap the preceding paragraph.  

See attached document backgroundcolor.odt and screenshot backgroundcolor.png .

Observed since many OOo versions in Win XP and Linux.

Confirmed for LibreOffice 3.4  340m1(Build:103) on OpenSuse Linux.

To reproduce the bug for yourself, download the attachment and add background colors to some of the already displayed paragraphs.

1. View -> Tools-> Formatting (Turn it on)
2. Highlight bottom paragraph in third set, apply color (eg blue). No problem yet.
3. Highlight top paragraph in third set, apply color (eg green)
4. Blue Highlighted paragraph leaks into the second

Thanks for the screenshots and document.

Comment 4 sasha.libreoffice 2012-01-30 04:30:11 UTC
reproduced in LibO 3.6.0 master on Fedora  64 bit
to reproduce, open first attachment, scroll text to most up, then to most bottom
problem appears if in Paragraph property:
 spacing "above paragraph" < "below paragraph"
Comment 5 A (Andy) 2013-05-02 20:10:14 UTC
reproducible with LO 4.0.2.2 (Win7 Home, 64bit)
Comment 6 HansPL 2013-10-07 12:20:39 UTC
Still defunct in LO 4.1.2.3 !
Comment 7 HansPL 2014-09-16 07:24:38 UTC
Three years now and no response…?  Like for many other annoying small bugs.  

How about a really resolute bug fixing release?

Please, do not change the version number, it shows the oldest version in which the bug has been found.

Best regards. JBF

Comment 11 HansPL 2016-05-17 11:34:05 UTC
Still present in 5.1.2.2.0+ / Linux!  

I would really wish that the LO team would spend time on fixing all those annoying year-old bugs instead of just ignoring them and unnecessarily adding gimmicks or changing the UI…  

It's five years now and this bug still defaces every single Operating Instructions we issue!  

If you really want LO not to be laughed at by all those MS Office users, please do give care and attention to the details.

Comment 13 Thomas Lendo 2017-05-26 10:43:32 UTC
Regina, OpenOffice has marked the same issue as duplicate of your CSS box model issue (https://bz.apache.org/ooo/show_bug.cgi?id=125316). Was that correct? If so then we can also mark this issue as duplicate of bug 106021.
Comment 14 Regina Henschel 2017-05-26 15:48:13 UTC
The problem here is not the box model directly. There exist two problems:

(1) To get the border around two adjacent paragraphs without a border line between the paragraph, the attribute style:join-border (20.292 in ODF spec part 1) is used. It has the text "The style:join-border property specifies whether a border for one paragraph is to be extended around the following paragraph." But is does not explain, how this has to be done. Especially it does not say, how to handle the margin-bottom of the first and margin-top of the second paragraph. This attribute is not based on any XSL-FO or CSS property, in contrast to the margin/border/padding properties.

(2) If two paragraphs of the same style follow directly, then the background color is extended into the margins between them. That is, what user want. But I doubt, that this is correct according to specification. It might be, that the specification has to be adapted. If the styles are different, then the transparent margin is kept. Word has a total different concept. 

It is not clear, what the correct/best solution is. Only the current rendering is surely wrong.
