Background text lost when converting ODP to PPTX using Aspose.Slides for Java

Using aspose-slides-18.11-jdk16 to convert ODP to PPTX.
Converting slide with background text. The text disappears because it is put in a zero size box in the top left corner of the background.

Code below:
Presentation presentation = new Presentation(inputPath);
presentation.save(outputPath, SaveFormat.Pptx);

@simon.wiseman,

I have worked with the presentation shared by you using Aspose.Slides for Java 18.12 and have been able to observe the issue. A ticket with ID SLIDESJAVA-37473 has been added in our issue tracking system to resolve the issue. This thread has been associated with the ticket so that we share notification with you once issue will be fixed.

Just to update you, the issue seems to be fixed using “aspose-slides-20.3-jdk16.jar”.

@simon.wiseman,

Thank you for your updates. Should we close the ticket on our end.
