I'm working towards migrating my VDAs to Server 2016 from 2012 R2. I've run into a couple of problems, and this is one of my latest.
The problem is that, upon initial connection to the server, the seamless applications are displayed partially blacked out. In the attached picture you can see Outlook and Word open, but the applications are unusable because 75% of the screen is blacked out. The applications still respond to keyboard and mouse input, including portions of the screen that are blacked out.
The issue does not happen every launch. While demonstrating to Citrix, it took me 4-5 times of logging off and on to the server to reproduce the issue. It doesn't appear to be related to the user having a profile on the machine (using UPM). This issue happened on 7.14, and still happens on 7.15.
This is not the other black screen issue where the logonui is displayed as a black window during the logon progress bar, this is different. However, the fixes for that are in place and that issue is no longer occurring.
The quick fix for this is to use the Reciever to disconnect and then reconnect by opening an application (even the same app works). Once the user is reconnected, the applications behave as expected.
Anyone else experiencing this?
