Created attachment 200405 [details] forum-mso-de-123568.xlsx Open and save the attached XLSX, forum-mso-de-123568.xlsx in Calc, then try opening it in Excel. -> Excel complains of a problem, when attempting repair, the error message is like this: "Removed Part: /xl/drawings/drawing2.xml part. (Drawing shape)" The problem is in one of the chart XMLs: <a:solidFill> <a:srgbClr val="7fffffff"/> </a:solidFill> "srgbClr" attribute is supposed to be RGB. This is a regression between 24.2 and 25.2. Bibisecting the issue was a bit difficult, because the bugdoc was also affected by bug 165503, which was only fixed recently. I'm also attaching a somewhat cut down version of the bugdoc, which only exhibited this issue and not bug 165503, this is the one that could be used for bibisecting. The issue started with the following commit in 25.8 (and in 25.2 by its backport): https://git.libreoffice.org/core/commit/1916957d0750b5471f23f17b2867a907e0e9e0e2 author Mohit Marathe <mohit.marathe.extern@allotropia.de> Wed Feb 19 12:21:19 2025 +0530 committer Sarper Akdemir <sarper.akdemir@allotropia.de> Sun Feb 23 16:24:43 2025 +0100 tdf#164936 oox: modify getColor method to include alpha
