--- Comment #27 from scott092...@aol.com ---
I am using LO-W 1:6.0.3-0ubuntu1 on Lubuntu Next 18.04, and found when opening
a previously-created document, that the pages did not line up.
Searching for LO-W bugs that referenced line-spacing, led me to this bug.
It sounded promising, and in reading the information in your site, and
following the breadcrumbs, I finally found the debian bug report:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=898116
where they reported that the bug had been:
"Fixed in version fonts-liberation/1:1.07.4-6"
The version I had was 1:1.07.4-5
So, I snagged the "cosmic" package (not yet available for "bionic")
and tried it, and it definitely solves the problem.

Thank all of you for investigating this, and helping lead me to a solution!

Ok, understood, makes sense now.
Then this is a Debian/Ubuntu problem and needs fixing by them.
Closing as NOTOURBUG.

See Caolán's comments in rhbz#1526510. It seems that old fontforge versions had
a bug which prevented it from reading/writing this bit correctly. So I guess
that problems started after debian/ubuntu updated their fontforge to the fixed
version, and that version was later used to build the liberation packages.

--- Comment #24 from Samuel Mehrbrodt (CIB)  ---
FWIW, I checked your document on Windows (with Liberation fonts downloaded from
Ubuntu bionic repo):
* MS Word 2013 displays page 2, strings 1-5 on the first page as well
* OpenOffice 4.1.1 displays only strings 1-54 on the first page as expected
(although I'm not sure if they bundle their own copy of the Liberation fonts).

I also investigated when this "ReallyUseTypoMetrics" setting was changed in
Liberation fonts. It has always been like it is since "first commit" in 2010. I
don't know why it changed now in Ubuntu and why it was different before.

Also this isn't related with bug 116498. Using the win metrics here doesn't
change anything.

Thx for all the links, indeed this seems silly to do to the Liberation Fonts.

That said - for the LibreOffice developer experience, what we have now is
fragile. This sucks, and leads to people ignoring test breakage beyond distro
maintainers.

You have a point though wrt distros - if they separate out the fonts into OS
packages, _that_ then should be part of any test run (and as you point out
would have caught the problem early on). But that's a downstream problem IMO.

I politely disagree.

We use many OS-provided functions. And using a font that has a strong guarantee
to be metric-compatible with MS fonts (and which thus should provide
predictable layout results) seems reasonable. I'd say that if in this case
maintainers would not simply ignore the unit test results and silenced the
relevant tests [1], it would be noticed and acted upon earlier. Otherwise, it's
unclear why would maintainers want to run unit tests at all - they would only
need to ensure that LO simply builds (reasoning that "it's upstream's
responsibility to make tests working")? IMO, the tests had shown broken distro
support rather early, which is generally important for LO and the impression it
produces.

(In reply to Maxim Monastirsky from comment #21)
> So it appears to be the same problem as in Bug 114434.

I forgot to mention that LO on Ubuntu 18.04 shows the same problem with any of
the package (1.7, 2.0) installed alone; so the 1.7 packaged fonts must also be
affected on Ubuntu.

FYI rebuilding the fonts-liberation2_2.00.1-5_all deb with this patch [1] seems
to solve the problem for me, at least under Ubuntu 18.04. So it appears to be
the same problem as in Bug 114434.

And worth a different bug report - unless LibreOffice itself ships the font
(and makes sure it's the first to be used during unit tests), it's probably a
bad idea anyway to rely on anything from the system, for something as fragile
as Writer layout...

See also bug 116498 - it is at least _possible_ LibreOffice started to be more
sensitive to otherwise benign changes in font tables.

Both Ubuntu Bionic and Debian Sid contain the same 2.00.1-5 version of the
package:

https://packages.ubuntu.com/bionic/fonts-liberation2
https://packages.debian.org/sid/fonts-liberation2

... and both contain the TTF fonts having version 2.00.2 (the version bump
happened at
https://salsa.debian.org/fonts-team/fonts-liberation2/commit/4a51c801d30ff165517563c2375b7540dd06589c;
not necessarily this specific commit has something to to with the problem).

So, this isn't an Ubuntu problem (apart from it taking not-thoroughly-tested
packages).

Rene: could you raise this against the font package maintainers please?

Also, installing libreoffice-gtk2 and starting LibreOffice with gtk2
(`SAL_USE_VCLPLUGIN=gtk libreoffice`) does not fix the problem by itself.

Looking at the screenshots, Lant is using the same LibreOffice version in both
Ubuntus, the only difference is that one uses gtk2 other gtk3 which I don't
think is relevant here

Thanks for the report. So this can either be that LO calculates the line
spacing differently in LO 6 than in LO 5.4.
Or the font metrics have really changed.

>From where did you get the Liberation Sans font? I guess it came with your
Ubuntu installation?
Can you paste the output of "apt search fonts-liberation" on both systems here?
There seem to be two different Liberation packages.

You could also try to run LO 5.4 on 18.04 and see if the behavior is the same.
Feel free to use the appimage versions for that:

So given the movement of the soft page breaks the different line height
calculation as rendered to canvas--and written at the appropriate line in the
flat ODF--does seem a valid graphics issue that needs attention.
