Description grv0815 2024-08-31 18:16:39 UTC

Source odt document and broken exported PDF.

The attached zip Archive include a writer odt document and the exported PDF:
 * defect.odt
 * defect.pdf

In the exported PDF, the transparent background of a shape is solid white filled and the color transition is lost, too (see pdf document in attached zip).

This was working in version 7.5
 

I used the Dev version because in the 24.8 stable version is the PDF export brocken (and already fixed in the dev version):

Looks like a dup of tdf#153279, please test modifying Skia options.

Retest with disabled Skia Rendering (see screenshot for the workaround) with the following version is ok, colour transitions and transparency are correct exported.

So, you are right and this bug is a duplicate of tdf#153279.
Big thanks goes to all involved and feel free to close it.
