Known issues

Notes

If a known issue has a workaround, it is provided after the description of the issue.

The following 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 the Registry Editor can be solved. Use the Registry Editor at your own risk. Be sure to back up the registry before you edit it.

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]

The Session limits settings for multi-session VDAs are declined in session hosts running Windows Server 2022, Windows 10 Enterprise multi-session, and Windows 11 Enterprise multi-session.[HDX-47001]

Microsoft confirms there is an issue retaining print settings between print jobs when using the Modern Print Dialog, which they are working to address. Their current projection is the first half of 2025. The Modern Print Dialog is enabled by default in newer OS versions such as Windows 11 and Windows Server 2025. The OS can be configured to use the legacy print dialog by taking the following action:

Open the Registry Editor.
Go to HKEY_CURRENT_USER\Software\Microsoft\Print\UnifiedPrintDialog
Right-click and select New > DWORD (32-bit) Value
Rename the value as PreferLegacyPrintDialog.
Right-click PreferLegacyPrintDialog and select Modify.
Set the value data to 1 and click OK.

If the uberAgent service is installed independently from the VDA (not through the VDA MetaInstaller), the uberAgent service must not be uninstalled when the VDA is uninstalled. [HDX-92242]

When publishing an application packaged with App-V, users may be unable to move or resize the application. As a workaround, set the following registry value: HKLM\SYSTEM\CurrentControlSet\Control\Citrix\wfshell\TWI\SeamlessSwclFlags(DWORD) = 2. This key must only be used to work around this specific issue and might cause reduced user experience with resizing and moving windows. [HDX-91796]

During a Citrix Virtual Apps and Desktops session, if a client monitor supporting audio playback is power cycled (turned off and then on), the name of the monitor’s audio playback device within the VDA’s Sound Control Panel (mmsys.cpl) changes from its correct, specific name to “Citrix HDX Audio”. This is an intermittent issue. As a workaround, close the VDA’s Sound Control Panel ( mmsys.cpl) window and then re-launch it. [HDX-87080]

When a new profile is created in NAPS2 version 8.x and a feeder-based scan is immediately initiated, the application might crash. The issue is specifically observed with NAPS2 version 8.1.4. [HDX-86985]

When attempting to add a new printer from within certain applications published on a Windows Server 2019 Virtual Delivery Agent (VDA), an error occurs preventing the printer from being listed or added. Specifically, an error message indicating that rundll32.exe cannot be accessed appears.

As a workaround, use a printer that is already visible in the application or add the printer so that it is available in the current session.

[HDX-86440]

If the device name is changed on the client machine while a session is active, the new name is not immediately reflected inside the session settings. This behavior affects both playback and recording devices.

As a workaround, to view the updated device name, you must disconnect from the session and then reconnect. Alternatively, logging out of the session and logging back in also resolves the issue.

[HDX-86327]

When multiple Chrome browser tabs, including those configured for Browser Content Redirection (BCR), are dragged and dropped simultaneously from one Chrome window to another, the redirected content might exhibit unexpected behavior. [HDX-81501]

If you move a tab with video content to a new window, playback might stop or the video might not appear. [HDX-92343]

When using Browser Content redirection with Browser Profile Sharing, SSO persistence with multiple profiles is not supported. [HDX-85325]

Windows 11 has a new UI feature to snap the windows on the desktop. A special toolbar appears on top of the desktop while the user drags the window. So multimedia overlay clipping logic is cutting the top/center area out, probably because of the new invisible/transparent window for this functionality.

As a workaround,

For more info, see Snap your windows section.
Refer How to disable “Snap your windows” feature. [HDX-91532]

When you use the Citrix Workspace app to access the VDA with Unicode input mode enabled, and either the “Unicode keyboard layout mapping” or “Automatic keyboard display” group policy is turned on, you might notice reduced performance in Microsoft Excel when scrolling through large pages. This issue occurs because UIAutomation APIs are incompatible with Excel.[HDX-91618]

Audio

When an audio device, such as a headset, is generically redirected using USB redirection to a Windows Server Virtual Delivery Agent (VDA) (for example, Windows Server 2019 or 2022), and multiple user sessions are simultaneously active on the same VDA, clicking the volume icon in the lower-right corner of the taskbar to adjust the settings can cause an unexpected crash of the Windows ShellExperienceHost.exe process. This issue primarily occurs in a session where the audio device is not actively redirected, but another session on the same VDA is utilizing generic USB audio redirection.

As a workaround, restart the Windows Explorer process (explorer.exe) in the affected session through the Task Manager. This might allow the volume icon to function without crashing.

Studio

Medium-strength SSL ciphers (SWEET32 vulnerability) are used in the Web Studio server. [STUD-35189]

Workaround:

Disable the vulnerable cipher suite on the Web Studio server using PowerShell:

 Disable-TlsCipherSuite -Name TLS_RSA_WITH_3DES_EDE_CBC_SHA
 <!--NeedCopy-->

Deprecated TLS 1.0 and 1.1 protocols are used in the Web Studio server. [STUD-35188]

Workaround:

Disable TLS 1.0 and 1.1 on the Web Studio server. Detailed steps are as follows:

Open Registry Editor.
Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols
Create the following subkeys if they don’t exist:
- TLS 1.0\Client
- TLS 1.0\Server
- TLS 1.1\Client
- TLS 1.1\Server
In each Client and Server key, create the following DWORD (32-bit) values:
- Enabled = 0
- DisabledByDefault = 1 (optional but recommended)
Restart the server to apply changes.

Machine Creation Services

The VMs created using InstanceType are not supported as a master image in Red Hat OpenShift environments. [PMCS-54272]

When creating an MCS machine catalog in a Red Hat OpenShift virtualization environment, you can’t use a master image and a machine profile that have different operating system types. This is due to how Red Hat OpenShift manages each OS type. Therefore, using a Windows VM as the master image with a non-Windows (example, Linux) VM as the machine profile, or the other way around, is not supported. [PMCS-54009]

In a Red Hat OpenShift environment, when the master image is joined to a domain, it might lose domain trust after being used for catalog creation. This issue affects Citrix Virtual Apps and Desktops 2503 and later versions due to a limitation in the OpenShift environment. The workaround is not to join domain in master images. Citrix is working with Red Hat to enhance network isolation capabilities. [PMCS-53794]

In a VMware environment hosted on AWS, the MCS machine catalog creation fails if the master image is vTPM enabled. This issue affects all Citrix Virtual Apps and Desktops versions and is due to a problem in the VMware environment. For assistance, contact VMware support. [PMCS-38514]
