Inkscape input and output

Description of problem:

I'm observing mis-placement of multi-line texts in .pdf converted
from .svg via Inkscape on pre-release Fedora 35.

On Fedora 34, they are rendered correctly.

Version-Release number of selected component (if applicable):

On Fedora 35, "incscape --debug-info" says:

Inkscape 1.1 (c68e22c387, 2021-05-23)

    GLib version:     2.70.0
    GTK version:      3.24.30
    glibmm version:   2.66.1
    gtkmm version:    3.24.5
    libxml2 version:  2.9.12
    libxslt version:  1.1.34
    Cairo version:    1.17.4
    Pango version:    1.49.1
    HarfBuzz version: 2.8.2
    Poppler version:  21.08.0

    OS version:       Fedora Linux 35 (Container Image)

On Fedora 34, "incscape --debug-info" says:

Inkscape 1.1 (c68e22c387, 2021-05-23)

    GLib version:     2.68.4
    GTK version:      3.24.30
    glibmm version:   2.66.1
    gtkmm version:    3.24.5
    libxml2 version:  2.9.12
    libxslt version:  1.1.34
    Cairo version:    1.17.4
    Pango version:    1.48.10
    HarfBuzz version: 2.7.4
    Poppler version:  21.01.0

    OS version:       Fedora 34 (Container Image)

How reproducible:

Always.

Steps to Reproduce:

Convert pubsub.svg in the attachment by Inkscape.

1. Run the command "inkscape -o pubsub-xxx.pdf pubsub.svg"

Actual results:

See pubsub-pango-1.49.1.pdf in the attachment.

Expected results:

See pubsub-pango-1.48.10.pdf in the attachment, which is converted
on Fedora 34.

Additional info:

On Fedora 35, by downgrading pango to 1.48.9
(https://kojipkgs.fedoraproject.org//packages/pango/1.48.9/1.fc35/x86_64/pango-1.48.9-1.fc35.x86_64.rpm),
correct rendering can be restored.

The same issue is reported at upstream Inkscape project at:
https://gitlab.com/inkscape/inkscape/-/issues/2864
Comment 1 Peng Wu 2021-10-29 03:33:39 UTC 
Could you report this issue to pango upstream?

Done.

Comment 4 Peng Wu 2021-10-29 06:39:40 UTC 
Thanks!
Comment 5 akiyks 2021-10-29 23:54:05 UTC 
In https://gitlab.gnome.org/GNOME/pango/-/issues/618#note_1299977,
Matthias Clasen commented that the change was intentional.

Switching Component to inkscape.
Comment 6 akiyks 2021-11-08 14:50:47 UTC 
A fix has been merged upstream at:

    https://gitlab.com/inkscape/inkscape/-/merge_requests/3630

I'd like to keep this ticket open until the fix reaches Fedora 35.

Thanks.

FWIW, I downloaded https://kojipkgs.fedoraproject.org//packages/inkscape/1.1.1/2.fc35/x86_64/inkscape-1.1.1-2.fc35.x86_64.rpm
and installed it on Fedora 35.

"inkscape --debug-info" says:

    Inkscape 1.1.1 (3bf5ae0d25, 2021-09-20)

        GLib version:     2.70.1
        GTK version:      3.24.30
        glibmm version:   2.66.2

        Poppler version:  21.08.0

        OS version:       Fedora Linux 35 (Container Image)

Now the multi-line texts in pubsub.svg are rendered right.

I'm waiting the update to be released for normal "dnf update".
