On a couple of Windows 8 computers I have seen the issue where I receive only white screen when someone shares their desktop with me in Lync 2013.
This applies to
- Fresh installed Windows 8 computer
- One year old Windows 8 computer
- Lync Peer to Peer collaboration
- The issue is consequent so it is not a specific deployment issue
- Lync conference
- All other attendees can see the screen fine so it is not an appsharing issue
- The issue is client related so it will be present for Lync Online as well as Lync on-premises
