Known issues in 2203 CU2

  • Attempts to upgrade Session Recording from Citrix Virtual Apps and Desktops 2203 LTSR CU1 to CU2 might fail. This error message appears:

    Unable to complete the installation.

    The installation did not complete because a problem occurred during initialization. The product will operate but performance could be diminished.

Known issues in 2203 CU1

  • VDAs might experience a fatal exception on tdica.sys and display a blue screen with a bug check code, 0x0000007E. [CVADHELP-19862]

Known issues in 2203 initial release

General

  • If you launch the app bar and then open the Connection Center menu in Citrix Workspace app for Windows, the app bar doesn’t appear under the server that hosts it. [HDX-27504]

  • If you use Citrix Workspace app for Windows and launch the app bar in a vertical position, the bar covers the Start menu or the system clock tray. [HDX-27505]

  • After installing the Skype for Business Web App Plug-in, webcams might not be enumerated and meeting pages on Firefox might not refresh automatically. [HDX-13288]

  • When you start an application from StoreFront, the application might not start in the foreground, or the application is in the foreground but might not have focus. As a workaround, click the icon in the task bar to bring the application to the front or in the application screen to bring it to focus. [HDX-10126]

  • When using Windows 10 1809 LTSC, VCLibs dependencies fail to install. [HDX-16754]

  • The combo box might not display properly when a user selects a combo box that is already in focus on the host. As a workaround, select another UI element and then select the combo box. [HDX-21671]

  • You have enabled Local App Access. If you start a Windows 2012 R2 VDA session, disconnect and reconnect the session, and then start a local application and maximize it, the VDA taskbar might truncate the application. [HDX-21913]

  • Citrix Hypervisor doesn’t support MCS full clone VMs with GFS2 SRs. [XSI-832]

  • If a Citrix Virtual Apps and Desktops deployment with its VMs hosted on Citrix Hypervisor 8.2 uses multiple GFS2 SRs in a single MCS catalog, VMs in the catalog cannot access the VDIs during deployment. The error “VDI is currently in use” is reported. [XSI-802]

  • When applications from Microsoft Office 365 build 16.0.7967 and later are published as applications from a Windows Server 2019 host, Office license activation fails. Citrix is working with Microsoft to address this Microsoft limitation. The supported workaround is to install Windows Server 2016 VDAs, which do not have Web Authentication Manager component that is misbehaving. [LCM-7637]

  • Session Manager terminates session launches when the Group Policy evaluation fails. This is to prevent user access to resources that are restricted through Group Policy. The following user-implemented fix provides a registry toggle for administrators to dismiss the enforcement, which helps end users to connect to sessions even if the Group Policy evaluation fails:

    HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\Ica\GroupPolicy

    Name: EnforceUserPolicyEvaluationSuccess

    Type: REG_DWORD

    Value: 0 (enables the current fix)

    [CVADHELP-20135]

  • Terminal Service running on a multi-session OS VDA might exit intermittently. The Event ID 7011 is logged in the System Event log with the following message:

    A timeout (30000 milliseconds) was reached while waiting for a transaction response from the TermService service.

    [CVADHELP-20259]

  • Your High Definition Experience (HDX) Audio devices disable when you are connecting to a single-session RemotePC or Workstation Virtual Delivery Agent (VDA) on a client that is enabling more than eight HDX Audio devices. As a workaround, choose one of the following:
    • Connect to a single-session RemotePC or Workstation VDA from a client that is enabling less than eight HDX Audio devices.
    • Enable the HDX Audio devices after the single-session RemotePC or Workstation VDA has launched.
    • Connect to a multi-session RemotePC or Workstation VDA.

    [CVADHELP-20164]

  • VDAs might experience a fatal exception on tdica.sys and display a blue screen with a bug check code, 0x0000007E. [CVADHELP-19862]

Studio

  • During site creation, after you add a license to enable Hybrid Rights License, public cloud hosts (such as Microsoft Azure, Google Cloud Platform, and Amazon Web Services) do not appear in the connection type list until the site creation completes. [STUD-17441]

Director

  • The Console link on Citrix Director > Machine Details does not launch the machine console in the Microsoft Edge 44 and Firefox 68 ESR browsers. [DIR-8160]

Graphics

  • When sharing a minimized app, the title bar of the app might also be shared. [HDX-33898]

  • Setting the policy View window contents while dragging to Prohibited does not work on ESXi and Hyper-V. [HDX-22002]

  • If you start a video preview using a 64-bit webcam app over Theora compression, the session might crash. [HDX-21443]

  • Some applications are limited to a maximum frame rate of 22 frames per second (FPS) instead of the default maximum of 30 FPS. A fix will be available in 2203 LTSR CU2. As a workaround, set the following registry value on the VDA:

    • Key: HKEY_LOCAL_MACHINE\SOFTWARE\Citrix\Graphics
    • Value: [REG_DWORD] EnableTimerPeriod = 1

    To activate the setting, you must disconnect and relaunch the session. [HDX-42319]

Printing

  • Universal Print Server printers selected on the virtual desktop do not appear in the Devices and Printers window in the control panel. However, when users are working in applications, they can use those printers. This issue occurs only on Windows Server 2012, Windows 10, and Windows 8. For more information, see CTX213540. [HDX-5043, 335153]

  • The default printer might not be marked correctly in the printing dialog window. This issue does not affect print jobs sent to the default printer. [HDX-12755]

Machine Creation Services (MCS)

  • In GCP environments, when you update the custom property of a provisioning scheme, the changes do not apply to the newly added machines in a catalog. To resolve this issue, after updating the custom property of a provisioning scheme, create a new updated image for the catalog. [PMCS-27672]

  • When you create a catalog with custom properties, and use Set-ProvScheme to change the provisioning scheme without updating the same custom properties as set during catalog creation, the properties that are not mentioned in the Set-ProvScheme are set to their default values. Also, if you set any custom property to its non-default value during catalog creation, it is overwritten to its default value after you run Set-ProvScheme. [PMCS-29858]

Third-party issues

  • Chrome supports UI Automation only for toolbars, tabs, menus, and buttons around a webpage. Because of this Chrome issue, the automatic keyboard display feature might not work in a Chrome browser on touch devices. As a workaround, run chrome --force-renderer-accessibility or you can open a new browser tab, type chrome://accessibility, and enable Native accessibility API support for specific or all pages. In addition, when you publish a seamless app, you can publish Chrome with the --force-renderer-accessibility switch. [HDX-20858]

  • In browser content redirection, after starting a YouTube video using the YouTube HTML5 video player, full-screen mode might not work. You click the icon in the lower-right corner of the video, and the video doesn’t resize leaving the black background in the full area of the page. As a workaround, click the full screen button, and then select theater mode. [HDX-11294]
