Microsoft Teams - Continuous layout switching on Primary display (Dual Screen)
This behavior is currently only impacting Dual Screen calls to Microsoft Teams meetings.
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 single screen experience on the main display, while getting the presentation on the secondary display. Workstreams with Microsoft are in progress to restore the Microsoft Teams dual-screen experience to its previous behavior.
