            Bug ID: 112093
           Summary: RTL Regression in justified Hebrew text
           Product: LibreOffice
           Version: 5.3.4.2 release
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: Writer
          Assignee: libreoffice-bugs at lists.freedesktop.org
          Reporter: schlomo at schapiro.org

I have a document with justified Hebrew text that looks correct in LOO till 5.2
and is broken in LOO 5.3 and 5.4.

The problem is that the text is justified only on the left side but not
correctly on the right side. Also the text is rendered differently (spacing,
line breaks) so that a text block that previously fit on a page doesn't fit any
more on a page. This is a 36 page brochure where this is really significant, I
first noticed the problem by the fact that the brochure suddenly had 37 pages
instead of 36.

The attached screenshots show the problem, look at the ragged right line in the
bad example.

To verify that the problem is caused by LOO I downloaded the following versions
and tried them all on the same system:

4.4.7.2 = OK
5.0.6.3 = OK
5.2.7.2 = OK
5.3.6.1 = BAD
5.4.1.2 = BAD

My system is Ubuntu 16.04.3 LTS x86_64. The following attachments should help
to analyze the bug:

- ODT file that has the problem (pages 4 and 5 in the screenshots)
- screenshot showing the bad rendering
- screenshot showing the good rendering in the older versions

To try out yourself I embedded the Hebrew fonts in the ODT so that you don't
have to install them yourself.
