Open and save attachment 125302 [details] from bug 100072 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 198 of /word/document.xml, which is the end of an <a:custGeom> element. The interesting part seems to be this: <a:gd name="GluePoint1X" fmla="*/ 0 w 284"/> <a:gd name="GluePoint1Y" fmla="0*logwidth/284"/> <a:gd name="GluePoint2X" fmla="*/ 284 w 284"/> <a:gd name="GluePoint2Y" fmla="0*logwidth/284"/> This is a regression from the following commit in 25.8 (and its 25.2 backport): https://git.libreoffice.org/core/commit/612891865a74777950ab7355a4d794fa5577c5fc https://cgit.freedesktop.org/libreoffice/core/commit/?id=612891865a74777950ab7355a4d794fa5577c5fc author Tibor Nagy <tibor.nagy.extern@allotropia.de> Thu Mar 20 11:47:57 2025 +0100 committer Nagy Tibor <tibor.nagy.extern@allotropia.de> Thu Mar 20 16:49:11 2025 +0100 "tdf#165670 PPTX export: fix glue points export regression" The similar XML part looks like this after exporting in a build preceding the regression: <a:gd name="GluePoint1X" fmla="*/ 0 w 2"/> <a:gd name="GluePoint1Y" fmla="*/ 0 h 285"/> <a:gd name="GluePoint2X" fmla="*/ 285 w 2"/> <a:gd name="GluePoint2Y" fmla="*/ 0 h 285"/> The part in the original document's XML looks quite different, so it's hard to compare against that. The document has a couple of other occurrences of this. Issue seems to be related to bug 166335's, and probably the use of "logwidth" in the formula is the problem.
