Symptoms
You share a screen with another user on the Microsoft Teams desktop client, and the other user requests control of your screen. In this situation, you see the user's request on the Sharing toolbar. However, you do not see an option to approve or deny the request. Even the Give Control drop-down menu doesn't react when you try to open it.
Cause
This issue occurs because the device that you are using doesn't have a graphics processing unit (GPU) installed, or GPU hardware acceleration is disabled. The Give Control drop-down menu doesn't work unless hardware acceleration is supported on the system. This behavior is by design.
