Created attachment 171732 [details] Test ODT with background Paragraph area gradient from ODT is not saved when it's saved as DOC or DOCX. Problem started from LO 4.4.0 and was reported in bug 88583 where bibisect was done and issue resolved for paragraph area fill. Paragraph area gradient is still wrong as seen in comparison attachment 171702 [details] of test ODT document attachment 112460 [details] saved as DOCX and DOC compared in LO 4.3, LO 7.2+ and MSO I add here extended test ODT, because saving in ODT of paragraph area gradient has a bug 132776.
Sorry, this is too vague for me to confirm. Could you please 1) point out which commit is the problematic one and 2) attach the old good and the new bad DOCX output? I'm confused how DOCX would represent gradient backgrounds, and even more unsure how this used to work in the past. :-) Thanks.

Bibisect is in https://bugs.documentfoundation.org/show_bug.cgi?id=88583#c7 Looks like this one in 44max: commit e642812606be49244f2f775e90169fbd1be29a97 Date: Sat Mar 14 22:28:59 2015 +0800 source-hash-7d9bb549d498d6beed2c4050c402d09643febdfa commit 7d9bb549d498d6beed2c4050c402d09643febdfa Author: Armin Le Grand <alg@apache.org> AuthorDate: Mon Jun 2 15:00:50 2014 +0000 Commit: Miklos Vajna <vmiklos@collabora.co.uk> CommitDate: Tue Jul 1 13:30:09 2014 +0200 Related: #i124638# Second step of DrawingLayer FillAttributes... for Writer objects, now added support for Paragraph and PageStyle (including Header and Footer) for direct attributes and style attributes (cherry picked from commit cc25c58f7052827bfebdc9fbeec668c8fa29ed1b) I don't see that MSO has paragraph color, but this was working somehow.
The < 4.4 versions converted the area fill gradient to paragraph background color (shading), which is a single color instead of two. As far as I see Word does not have an equivalent of paragraph background gradient.
*** Bug 142163 has been marked as a duplicate of this bug. ***
I think this bug report should be resolved as "not our bug". The ooxml format has no way to store a gradient as background of a paragraph. The paragraph background is set in the w:shd element (17.3.1.31 shd (Paragraph Shading)). And that has only solid fill and pattern.
But: - it used to work, how - can it be saved in LO namespace, until and unless DOCX has it.
(In reply to Timur from comment #8) > But: > - it used to work, how > - can it be saved in LO namespace, until and unless DOCX has it. Do you mean, to add something to DOCX, so that the gradient is recreated on opening? Although Word would not be able to display it? Why would you need it? You can save as .odt to keep the gradient.
Yes, but on 2nd thought better to save as what MSO can read, as it was.
Before LO fill was overhauled to use XATTR_FILLGRADIENT, I assume that this was a RES_BACKGROUND gradient that on export was converted to one solid colour. In this particular instance it looked good. Since DOC/X does not have these gradients, it must be emulated. And the end result will very much depend on the situation and the viewer's perception of whether the chosen colour out of the gradient is "good" or not. Perhaps it is best to not do anything at all (like we are currently doing) to emphasize that MS formats can't feature-match LO in this area. It forces the user to design the document correctly for their output of choice.
