VDA for single-session OS

Printing

  • On a VDA for Desktop OS, attempts to print a file with a mapped client printer might fail. The issue occurs when the VDA is installed on Windows 10 version 1903. [CVADHELP-13357]

  • With the non-default fonts (for example, the barcode font CCode390) installed on the VDA Version 7.18 or later, a printing issue might occur when you update XenApp and XenDesktop from Version 7.17 to 7.18 or later. As a result, the barcode font might not print when you print a document from a session. [CVADHELP-12454]

Session/Connection

  • When you play back audio in a user session, you might hear a popping sound. [CVADHELP-11241]

  • On Citrix Receiver for Windows, you might hear sounds intermittently when you play audio. [CVADHELP-11440]

  • On some user devices, it might take a long time to launch a second application if you set the graphics cards to ON. [CVADHELP-12387]

  • The optimized webcam feature of Media Foundation-based video applications might not work for some APIs. [CVADHELP-12427]

  • When you change visual effects within a user session, the UserPreferencesMask value under the registry key HKEY_CURRENT_USER\Control Panel\Desktop might not be updated to the new value.

    To enable the fix, create the following registry key:

    HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\CtxHook\AppInit_DLLs\UI Tweak\SystemPropertiesComputerName.exe

    Name: HookProcess

    Type: REG_DWORD

    Data: 1

  • Attempts to copy text from a published application to an endpoint might fail when using Citrix Workspace app 1902 for Windows or later. [CVADHELP-12945]

  • An access violation can cause the wfshell.exe process to exit unexpectedly. As a result, an attempt to launch an application fails. [CVADHELP-13032]

System exceptions

  • When you attempt to export video clips on a VDA for Desktop OS, certain third-party applications might exit unexpectedly. [CVADHELP-11303]

  • Servers might experience a fatal exception on tdica.sys and display a blue screen with bug check code SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (7e).

VDA for multi-session OS

Printing

  • With the non-default fonts (for example, the barcode font CCode390) installed on the VDA Version 7.18 or later, a printing issue might occur when you update XenApp and XenDesktop from Version 7.17 to 7.18 or later. As a result, the barcode font might not print when you print a document from a session. [CVADHELP-12454]

Session/Connection

  • When listening to audio with the audio quality set to high, you might hear a popping or a crackling sound. The issue occurs when you pause the audio for a few seconds and then start the audio again. [CVADHELP-10657]

  • On some user devices, it might take a long time to launch a second application if you set the graphics cards to ON. [CVADHELP-12387]

  • When you change visual effects within a user session, the UserPreferencesMask value under the registry key HKEY_CURRENT_USER\Control Panel\Desktop might not be updated to the new value.

    To enable visual effects to be retained, create the following two registry keys:

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Citrix
    Name: EnableVisualEffect
    Type: REG_DWORD
    Value: 1
    

    and
