Created attachment 175604 [details] WordArt shape 'Button' Open attached document. It contains a shape type "Button" from section "Follow Path" in "abc Transform" (=WordArt) in PowerPoint. The shapes form section "Follow Path" are imported with ScaleX=true in property 'TextPath' in 'CustomShapeGeometry'. That means, that the text keeps its original font size as long as there is enough place. That happens for the two arcs of the shape, but in the middle part, the text is stretched. The second attachment has a screenshot with comparison of rendering in PowerPoint and LibreOffice. This is not an import error but likely a error somewhere in EnhancedCustomShapeFontWork.cxx
