Known Issues

Following are the known issues with the release of Userful™ 8.8.1

• If two overlapped video wall zones share the same control station:

• Playing interactive session on first zone and any other session on the second zone, first zone may keep on restarting and second zone may not start (14319)

Workaround: Select different control stations for the overlapped zones.

• Capturing a PC with color space set to RGB may show artifacts mostly visible with text on the display (14308)

• Direct Sync feature without Nvidia Offload is not supported with Blackmagic DeckLink Capture session container (14232)

Workaround: Disable Direct Sync or enable Nvidia Offload Support and Direct Sync before using Blackmagic DeckLink session container

• Switching of video wall zones to different session containers may lead to system instability with Entry-Level Appliance (14196)

Workaround: Entry-Level Appliance is recommended only for smaller deployments playing signage content.

• If the last played video wall zone contains a station, which is the control station of other zones:

• Playing/Stopping the last played video wall zone will restart the content playback on the previous played zone (14189)
• Playing non-Interactive session container (e.g. Signage Player), the last played zone will get the sound output

Workaround: Control station of a video wall zone should not be the part of the other video wall zone

• Changing static IP address of a NIC that has a DHCP server assigned to it, does not update the DHCP settings (14169)

Workaround: Disable the DHCP server when changing IP address, wait until the UCC acknowledges that DHCP is fully offline and then enable the DHCP server

• Changing the DHCP settings under Control Center > System Operations > Network Settings takes several seconds to take effect (14167)

• Transitioning from Video Capture session container to Signage Player session container may result in loss of audio while using Preset Settings feature (14163)

• Playing signage content over stand-alone 1080p display may result in video stuttering (14077)

Workaround: Lower the bitrate of the video

• Stopping the last played overlapped video wall zone with Direct Sync disabled may result in white screen on the overlapped portion (14058)

• Resetting a station playing signage content with Direct Sync disabled restarts all other stations playing the same signage content (14034)

• Mapping multiple stations to Video Capture session container may cause kernel panic (13933)

Workaround: Enable "Mirror Groups" when you map multiple stations to Video Capture session container

• Switching zones between different session containers with Direct Sync enabled may restart the existing video wall (13384)

• Stations mapped to Linux Desktop playing youtube videos may have playback issues (13412)

Workaround: Disable "Use Hardware Acceleration when available" option under Web Browser settings

• DVD Player session container fails with Nvidia Offload support (13387)

Workaround: Disable Nvidia Offload support when using DVD Player session container

• Broadcast alerts and Show Station ID will not function when Direct Sync is enabled (13370)

• Transitioning from Video Capture session container to other session containers may result in loss of audio (13305)

Workaround: Assign the video wall or display to a different Signage Player session container and then assign it back to the intended session container

• Avoid opening Control Center via multiple browser windows (13294)

• Manage Licensing > Backup License option does not work with Stand-alone Userful Control Center (13266)

Workaround: Use web browser (chrome or firefox) to access Control Center

• Control Center may not reflect correct network settings when system is configured using DHCP (12950)

• Webcams connected to Network zero-client for video capturing are not supported (12939)

• GPU-Accelerated video walls do not support mirroring (12828)

• Lowering the display resolution of 1080p monitor to 640x480 may cause black screen (12562)

• Plugin/out of USB hub from an Atrust m321 zero-client device do not wake station from DPMS sleep (12181)

• Extended Support value does not show up in the "Manage Licensing" dialog in Control Center (12116)

Workaround: Contact your Userful representative to confirm the status of your extended support license

• Using Blackmagic Design DeckLink Duo HDMI Capture card, transitions between HDMI capture sources can result in a flicker of 0.5 to 1.0 seconds (11918)

• The Same user logged in on multiple stations cannot output sound correctly (11672)

Workaround: Use "AutoLogin" session container for multiple sessions

• DisplayLink, TN-750 and TN-502 devices are not supported with video wall solution (11668) (11654)

Workaround: Use an SMSC-based zero-client for video demanding applications

• The Show Station ID feature may not work on stations running a Linux Desktop which has been locked by the screensaver (11589)

Workaround: Unlock or disable the screensaver, then press Show Station IDs button in Control Center

• SMSC network zero clients connected to fast ethernet switch may get a black screen when changing session containers (12005)

Workaround: Use a Gigabit Switch for the zero clients and the Userful host

• When Duplicate IP address are detected in the network, the warning message displayed in Control Center is cramped (11150)

Workaround: This is a cosmetic issue and would not affect any functionality

• Blackmagic session container lists down resolutions not supported by the hardware (10870)

Workaround: Confirm that your HDMI source media supports the resolution and frame-rate the HDMI Capture session is configured to use.

• Images larger than 10800 x 8552 pixels may not display correctly (10769)

Workaround: Increase the slideshow time interval based upon the time required to load the image file

Workaround: Use DVI monitors with Atrust m321 zero client device

• Once an Artistic Layout video wall is created and saved, you cannot switch it back to a Grid Layout

Workaround: Delete the Artistic Layout configuration and create a new video wall

• Mapping a GPU-Accelerated Video Wall to supported session containers disables onboard station
