Created attachment 144037 [details] Original file as saved by PowerPoint 365 With the patch for bug 116350 LibreOffice can read font effects 'transformation'. But if such file is save (without any changes) back to pptx, then the objects get shape filling. I know, that ODF does not distinguish between character filling and shape filling in Fontworks, but as long as LibreOffice is still in pptx format, it should remember, that the objects had no shape filling. At least no shape filling should be written, because that is more likely than a filled shape in case of fontwork.
The attached file is generated from the file from bug 116350, but now I have removed the character shadow. And I have saved it in non-strict format, so that the resave by LibreOffice can be opened in PowerPoint. [Resave of strict format produces invalid pptx file, see bug 119087.] Szymon, I have put you on CC, because you are currently working in that area.

But there are still fillings where they should not be. See slides 6, 10, 12, 14 and 16.

No, my build includes that commit and I still see wrong fillings. Use the attached file "Original...", re-save it by LibreOffice and look at it in PowerPoint. The wrong fillings are on slide 6, 10, 12, 14 and 16.
