Shape Background Colors Are Not Consistent but Values Are Equal


I am writing to you about the problem we encountered in working with MSO PowerPoint document using the Aspose Slides for Java library (v21.10). We are using Ubuntu 22.04 LTS and OpenJDK 11.0.13.

When we try to save the PPT file as a new PPTX file (with no modifications), there is no visual consistency in shape background colors (screenshot provided). However, assert statements pass so we could not prove it that way. Manual testing is required. The problem occurs on the second slide of a given presentation.

In the attachment below, you can find the ZIP file with test code, source PPT file as well as screenshot of source and target presentations.

Best regards!
