Incorrect rendering as image

(Attached: Details.zip containing deck.ppt, PowerpointRendering.jpg and AsposeRendering.jpg).

PowerpointRendering.jpg was generated by doing “Save As .jpg” in powerpoint for the only slide in deck.ppt.

AsposeRendering.jpg was generated by calling getThumbnail on the slide object with Aspose.

Notice how the background image in AsposeRendering.jps is messed up (it’s a bunch of vertical lines).

Have you observed that bug before?
Is there a workaround?

Thank you.

Thank you for this example. We will try to fix it asap.
