Citrix Workspace App 1812 Download

Display looks like below while re-docking the Notebook and reconnecting the session using Workspace App for Windows 1812:
The screen remains grey and only shows the scroll bars mentioned above.
Regarding the scroll bars, it seems like the session still knows the resolution of the two monitors, but won't scale to full screen anymore.
1812Because it's a full screen view of the screen the user then has no other choice than to restart the session to get this fixed.
This issue is seen only when working with dual monitor and full screen session without desktop viewer.
Steps to reproduce the issue:
  1. Start a new Citrix session on a notebook with docking station an two monitors.
  2. The notebook remains closed.
  3. Remove the notebook from the docking station without opening the notebook.
  4. Reconnect the notebook to the docking station without opening the notebook.
  5. You can find a print screen in the attachment showing the issue with 18.12 after reconnecting the docking station.
