We have confirmed this behavior is specific to the Microsoft Teams Light Web client and have reported the issue to Microsoft. As a mitigation, we are applying a service-side change to stabilize dual-screen presentation behavior. In dual-screen calls, shared content is expected to remain on the primary display.
The mitigated behavior resembles a “mirrored screen” experience. However, the system is still rendering two distinct compositions (e.g., separate gallery views alongside shared content). Workstreams are in progress to restore the Microsoft Teams dual-screen experience to its previous behavior.
If you require a more consistent experience during this period, Synergy SKY can provide an alternative configuration that improves layout stability. Please contact support@synergysky.com for details and system requirements.
