Known issues
The following issues have been identified in this release:
-
When you join SUSE 15 VDAs on AWS to the Windows domain by using PowerBroker Identity Services (PBIS), attempts to launch sessions from these SUSE 15 VDAs fail. [LNXVDA-10874]
-
Non-seamless published applications might exit shortly after launch. The issue occurs after a Mutter upgrade to a version later than mutter-3.28.3-4. To work around the issue, use mutter-3.28.3-4 or earlier. [LNXVDA-6967]
-
The Linux VDA does not work as expected when you use NVIDIA GRID 3D cards without enabling HDX 3D Pro. The issue occurs on RHEL 7.7 and earlier, SUSE 12.5 and earlier, and Ubuntu 16.04. The reason is that multiple OpenGL libraries cannot coexist in the graphics systems of these Linux distributions.
-
An unexpected window appears during file download. The window does not affect the file download functionality and it disappears automatically after a while. [LNXVDA-5646]
-
The default settings of PulseAudio cause the sound server program to exit after 20 seconds of inactivity. When PulseAudio exits, audio does not work. To work around this issue, set exit-idle-time=-1 in the /etc/pulse/daemon.conf file. [LNXVDA-5464]
-
libtcmalloc 4.3.0in SUSE 12.5 might cause processes to exit unexpectedly. -
The
ctxhdxservice might exit unexpectedly on the Ubuntu 16.04 and SUSE 12.5 VDAs. The issue occurs with the GNU C Library (glibc) Versions 2.22 through 2.24. The issue is fixed inglibc 2.25. If you are using the SUSE 12.5 distribution, you can install the patch that SUSE provides for fixing the issue. No fix is available for Ubuntu 16.04 at the time the Linux VDA is released. [LNXVDA-4481] -
Sessions cannot be launched in Citrix Workspace app for Linux when SSL encryption is enabled and session reliability is disabled. [RFLNX-1557]
-
The
indicator-datetime-serviceprocess does not consume the $TZ environment variable. When the client and session locate in different time zones, the unity panel on Ubuntu 16.04 Unity Desktop does not show the time of the client. [LNXVDA-2128] -
Ubuntu graphics: In HDX 3D Pro, a black frame might appear around applications after resizing the Desktop Viewer, or sometimes, the background can appear black.
-
Printers created by the Linux VDA printing redirection might not be removed after logging out of a session.
-
CDM files are missing when a directory contains numerous files and subdirectories. This issue might occur if the client side has too many files or directories.
-
Only UTF-8 encoding is supported for non-English languages.
-
Citrix Workspace app for Android CAPS LOCK state might be reversed during session roaming. The CAPS LOCK state can be lost when roaming an existing connection to Citrix Workspace app for Android. As a workaround, use the Shift key on the extended keyboard to switch between upper case and lower case.
-
Shortcut keys with ALT do not always work when you connect to the Linux VDA using Citrix Workspace app for Mac. Citrix Workspace app for Mac sends AltGr for both left and right Options/Alt keys by default. You can modify this behavior within the Citrix Workspace app settings but the results vary with different applications.
-
Registration fails when the Linux VDA is rejoined to the domain. The rejoining generates a fresh set of Kerberos keys. But, the Broker might use a cached out-of-date VDA service ticket based on the previous set of Kerberos keys. When the VDA tries to connect to the Broker, the Broker might not be able to establish a return security context to the VDA. The usual symptom is that the VDA registration fails.
This problem can eventually resolve itself when the VDA service ticket expires and is renewed. But because service tickets are long-lived, it can take a long time.
As a workaround, clear the Broker’s ticket cache. Restart the Broker or run the following command on the Broker from a command prompt as Administrator:
klist -li 0x3e4 purge <!--NeedCopy-->This command purges all service tickets in the LSA cache held by the Network Service principal under which the Citrix Broker Service runs. It removes service tickets for other VDAs and potentially other services. However, it is harmless – these service tickets can be reacquired from the KDC when needed again.
-
Audio plug-n-play is not supported. You can connect an audio capture device to the client machine before starting to record audio in the ICA session. If a capture device is attached after the audio recording application has started, the application might become unresponsive and you must restart it. If a capture device is unplugged while recording, a similar issue might occur.
-
Citrix Workspace app for Windows might experience audio distortion during audio recording.
