title: SSIS package shows blank screen in design mode
body: <p>I created a SSIS package using <code>SQL Server data tools 2015</code> a week back.
  And today i opened the package and it just shows the blank screen.</p>
  
  <p>I read about this issue <a href="https://social.msdn.microsoft.com/Forums/sqlserver/en-US/5b4faddc-5723-44fb-926d-e5a92dc8fc0f/ssis-designer-is-solid-white?forum=sqlintegrationservices" rel="noreferrer">here</a> and it seems that was the defect in earlier versions and it is fixed.</p>
  
  <p>Did anyone face this issue in data tools 2015? How can i fix it and save my package?</p>
