Is anyone else seeing the “Shared With” UI break specifically on List items after installing KB2899508? We are seeing this issue in multiple environments.
We went through the updates one by one in a Dev environment and found that the issue is triggered with this update:
November 11, 2014 update for SharePoint Foundation 2013 (KB2899508)http://support.microsoft.com/kb/2899508
Here is another thread on Social TechNet where others are starting to see similar behavior:
We have a ticket open with Microsoft on this issue, and were notified today that they are able to duplicate the behavior and are looking into it further.
