Known Issues 11.01.100

Citrix

With activated DRI3 and an AMD GPU Citrix H.264 acceleration plugin could freeze. Selective H.264 mode (API v2) is not affected from this issue.

Citrix has known issues with GStreamer1.0 which describe problems with multimedia redirection of H.264, MPEG1 and MPEG2. GStreamer1.0 is used if browser content redirection is active.
Browser content redirection does not work with activated DRI3 and hardware accelerated H.264 deep compression codec.
Citrix StoreFront Login with Gemalto smartcard middleware does not detect smartcard correctly if the card is inserted after start of Login.
As a workaround, insert the smartcard before starting StoreFront Login.
When using Citrix Workspace App 18.10 in combination with Philips Speech driver, the session occasionally does not properly terminate at logoff and hangs.
As a workaround, usage of Citrix Receiver 13.10 is recommended when Philips Speech driver is needed.
Citrix H.264 acceleration plugin does not work with enabled server policy Optimize for 3D graphics workload in combination with server policy Use video codec compression > For the entire screen.

VMware Horizon

External drives are mounted already before connection, do not appear in the remote desktop.
Workaround: Mapping the directory/media as a drive on desktop. The external devices will show up within the media drive then.
Client drive mapping and USB redirection for storage devices should not be enabled both at the same time.
- On the one hand, when using USB redirection for storage devices: The USB on-insertion feature is only working when the client drive mapping is switched off. In the IGEL Setup client drive mapping can be found in: Sessions > Horizon Client > Horizon Client Global > Drive Mapping > Enable Drive Mapping. It is also recommended to disable local Storage Hotplug on setup page Devices > Storage Devices > Storage Hotplug.
- On the other hand, when using drive mapping instead, it is recommended to either switch off USB redirection entirely or at least deny storage devices by adding a filter to the USB class rules. Furthermore, Horizon Client relies on the OS to mount the storage devices itself. Storage Hotplug on setup page Devices > Storage Devices > Storage Hotplug has to be enabled and the Number of storage hotplug devices has to set to at least 1.

Parallels Client

Native USB redirection does not work with Parallels Client.
For using the new FIPS 140-2 compliance mode, it is necessary to connect to the Parallels RAS once with disabled FIPS support.

Smartcard

In seldom cases, the authentication hung when using A.E.T. SafeSign smartcards.

Multimedia

Multimedia redirection with GStreamer could fail with the Nouveau GPU driver.

Base system

On NVIDIA GPU drivers, the reported resolutions of a display may contain unsupported resolutions. When any of those are configured, there are visual bugs (e.g. the desktop does not render properly).
