Default Download PDF in Quotes is not working in 10.2 SugarCRM Instance

Hi Everyone,

We have installed Sugar 10.2 Developer builds on our server. We are facing issues while downloading the download PDF in the Quotes module.

Not able to download on any 10.2 Sugar Instance installed on our servers.

While trying to download getting an error in Sugarcrm.log file like TCPDF error  - Some data has been already Output,cant sent data file.

Attaching the screenshots for more information.

I am just wondering is this expected behavior in Sugar 10.2 or any Bug.

Would be great and helpful, if any of the team or SugarTeam has some solution for this. Many Thanks in Advance.
