Overview: Local App Access is designed for Full-Screen sessions of virtual desktops that span all monitors. This feature is supported and intended to be used with a connection to a single desktop VDA, not multiple concurrent VDAs.
Scenario 1: If a Local App Access enabled virtual desktop session is opened and resized to a single monitor on a multi-monitor endpoint and then a non LAA enabled desktop session is opened on another monitor of the same endpoint, various graphic issues such as flickering may exhibit. In addition the user experience may be confusing if the virtual desktop session is opened in windowed mode or does not cover all monitors.
Resolution : The Local App Access Virtual Desktop Session must be opened full screen and span all available monitors in order to function as intended.
Scenario 2: If a virtual desktop session is opened with an odd numbered resolution (either height or width), maximizing a local app within the desktop session may not respect the work area borders of the session and overlap other elements of the desktop.
Resolution: Citrix is aware of this issue and is working on a fix in a future current release of the product
