Following are the known issues with the release of Userful™ 8.8

- Workaround: Disable Direct Sync before creating Blackmagic DeckLink session container or Enable Nvidia Offload Card Support and Direct Sync feature installed in the system
- If a video wall has overlapping zones with the same control station then:
- Playing signage content over the overlapping zones simultaneously will stop the content playback on the last played zone (14229)
- Playing Interactive session containers (e.g. Web Browser) will stop the content playback on a lower stack order zone (14189)
- Playing non-Interactive session container (e.g. Signage Player), the last played zone will get the sound output (14189)
- Workaround: Do not include the control station of one video wall zone into any other overlapped zone

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