            Bug ID: 132492
           Summary: Regression: Incorrect rendering of SVG files
           Product: LibreOffice
           Version: 6.4.3.2 release
          Hardware: All
                OS: Linux (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: graphics stack
          Assignee: libreoffice-bugs at lists.freedesktop.org

Description:
Draw, impress, writer and calc render some svg images incorrectly, with missing
elements.

Interesting enough:

- LibO impress renders correctly the same svg image
- Exporting to pdf leads to a pdf file where the image is rendered correctly
- Asking draw to "break" the svg image, that is to transform it from svg in its
internal object representation causes the image to be shown (almost) correctly.
I.e. the missing elements are there and the only issues are some misalignments.

I am experiencing this in LibO 6.4.3.2 re-opening slide lectures I made about
the same time in the past year (i.e., spring 2019) and I am sure I saw no issue
like that at that time.

Hence there is some regression in the svg rendering paths.

Issue does not seem to be influenced by hardware acceleration or opengl.

Steps to Reproduce:
1. Open the test document attached to this bug.
2. See the image
3. Start a presentation or export to pdf and view the pdf
4. See that the image is different.

Actual Results:
SVG image is rendered incorrectly

Expected Results:
SVG image should be rendered correctly


Reproducible: Always


User Profile Reset: No


OpenGL enabled: Yes
