Symptoms
Assume that you use a whiteboard in Microsoft Skype for Business 2016, and make lots of text annotations. When you save this whiteboard as the PNG format, the text annotations near the edge are missing from the PNG.
This issue occurs because the size of the PNG that's required to save all the annotations is computed incorrectly.
Resolution
To fix the issue, install the February 7, 2017, update (KB3141501) for Skype for Business 2016.
