Description Aron Budea 2025-04-24 14:26:35 UTC 
Open and save attachment 99563 [details] from bug 79062 back to DOCX, then try opening it in Word.

=> Word fails to open the file cleanly.

Observed using LO 25.8.0.0.alpha0+ (736998ccef0bacdd2bbf038c98dacfbe654f1a4d) / Windows.

If one:
- unzips the saved DOCX,
- executes the following command (can be done in Linux/Cygwin, needs xmllint installed): find . -name "*.xml" -type f -exec xmllint --output '{}' --format '{}' \;
- rezips the result with .docx extension

Then Word points to line 105 in word/footnotes.xml, which is the first line of this part:
<w14:schemeClr w14:val="light2">
  <w14:tint w14:val="85000"/>
  <w14:satMod w14:val="155000"/>
</w14:schemeClr>

This is a regression from the following commit in 25.2:

"tdf#156333 Adding a tint/shade values to the model"

The similar exported part looks like this when exported in a build preceding the regression:
<w14:schemeClr w14:val="bg2">
  <w14:tint w14:val="85000"/>
  <w14:satMod w14:val="155000"/>
</w14:schemeClr>
