Renders grey rounded outline box with PDF from MS PowerPoint

Version: 3.53.5 Android SDK
License: Premium

Issue:
A particular PPT-converted PDF file renders a grey outline box when using Radaee SDK, but is not displayed when using Android Adobe PDF Reader. We did not do anything special in the rendering logic (just followed the SDK sample). Can you please advise if this is a limitation / issue in the Radaee SDK? Thanks

See attached screenshot.

And please see source PPT and converted PDF in attachments. The PPT file is converted to PDF using default settings in Microsoft Powerpoint 2010.

i have just make screen-shot for this PDF file.
and no problems found.
i guess, you are using old version of SDK.
screen-shot as below:

Thank you. Verified that upgrading to 3.54 Android SDK fixed this issue.
