OleObjectFrame oleShape = (OleObjectFrame)shape;
I have worked with the presentation file shared by you and have generated the slide thumbnail using Aspose.Slides for Java 15.6.0 on my end. I have been able to reproduce a mild issue in text rendering as against the results achieved on your end. For your kind reference, I have attached the generated thumbnail as well.I have created an issue with ID SLIDESJAVA-34997 in our issue tracking system to further investigate and resolve the issue. This thread has been linked with the issue so that you may be automatically notified once the issue will be resolved.
We are sorry for your inconvenience,
