Transparent TextBox Is Rendered as Grey when Converting PPTX to JPEG/PDF in C#

We’re having issues with a textbox that isn’t displayed in PowerPoint (because it’s transparent) get rendered by Aspose Slides. We’re using Aspose.Slides.NET6.CrossPlatform@24.8.0. We’ve tested both with and without license and the grey box is rendered regardless. We’d like the textbox to stay hidden in the output.

Attached is a repro, including a Dockerfile as we’re running in Ubuntu in production. The bug can be reproduced by running in Windows as well.
