The Citrix Virtual Apps and Desktops 7 2109 release contains the following issues. Components and features that are documented separately have their own known issues articles.

This warning applies to any workaround that suggests changing a registry entry:

Warning:

Editing the registry incorrectly can cause serious problems that might require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Be sure to back up the registry before you edit it.

General

  • If you install Citrix Workspace app on the VDA and upgrade the VDA, the client webcam may not properly redirect 32-bit applications running in the virtual session. To work around this issue, see CTX291350. [CVADHELP-16854]

  • 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]

  • In the Chrome browser with browser content redirection in effect, when you click a link that opens a new tab, the tab might not open. As a workaround, select Always allow pop-ups and redirects in the Pop-ups blocked message. [HDX-23950]

  • 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]

  • 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]

  • Windows Defender might occasionally cause Citrix Scout to take longer than usual to collect information located at C:\Program Files\Citrix.

As a workaround, follow the steps below:

  1. Go to Start > Settings > Update & Security > Windows Security > Virus & threat protection.
  2. In the Virus & threat protection settings, click Manage settings.
  3. Under Exclusions, click Add or remove exclusions.
  4. Add C:\Program Files\Citrix\Telemetry Service\ScoutUI.exe or C:\Program Files\Citrix\ as an exclusion. [XAXDTELE-3248]

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]

  • If you upgraded to Director 7 1903 or later and did not clear the browser cache (not selecting the Disable cache check box), previously created custom reports are lost. Also, Director displays an Unexpected Server error on the Custom Reports tab. UI design differences between previous and current Director versions can cause this issue. To view earlier custom reports and create new ones, disable cache and perform a hard refresh. [DIR-7634]

Graphics

  • 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]

  • Skype Universal Windows app (UWA) launches with a black background. Sometimes, this background occupies the client’s entire screen. [HDX-22088]

  • DPI might not match during a session running on Windows Server 2016 or 2019 when the DPI is changed on the client and the session is reconnected. As a workaround, resize the session window to match the DPI. [HDX-17313]

  • Sometimes, an application launches in the background while another application is in focus. As a result, local window ordering is lost. [HDX-21569]

  • The XenCenter console might display a blank screen after disconnecting a XenDesktop session. As a workaround, send CTLR+ALT+DEL to the XenCenter console to make the console screen appear. [HDX-17261]

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]

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]

  • When File Explorer (explorer.exe) is published as an application on Windows Server 2019, displays do not refresh correctly after creating, renaming, or deleting a folder. As a workaround, create the following registry key.[CTX263595]

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\EXPLORER.EXE

    DWORD: DontUseDesktopChangeRouter

    Value: 1
