Open attached docx file which includes text lines with character direct, character style (Style2) and paragraph style (Style3) utilizing font effect transparency setting.
The lines in the file explain which is using which type of formatting.
LibreOffice retains the information for paragraph styles, you can apply it to new lines of text export back out to docx with the setting in tact.
Only the lines with Style3 (paragraph style) fail to properly display in LibreOffice.

@Miklos, I thought you might be interested in this issue since it's related to text transparency
It seems like transparent character properties are a new feature in LO 7.
DOCX import support came in 7.0's https://cgit.freedesktop.org/libreoffice/core/commit/?h=libreoffice-6-4&id=3a749d7278bbe65cfc063e64460df8af6bc2af47
In the character properties font-effects UI there is a setting for it, added in 7.0's https://cgit.freedesktop.org/libreoffice/core/commit/?h=libreoffice-6-4&id=6d6e80435fd7f71342c429a67759a7b7b280cc55
However, in the character and paragraph STYLE properties, that setting is missing.
Is this a duplicate of bug 130456?
