Hi @Hugo
Do you mean that "giving control" doesn't work when sharing your screen in Teams? If you disable GPU hardware acceleration, you will have an issue where the Give Control drop-down menu does not work.
If not, please try troubleshooting the issue below:
1)Make sure your network connection is stable, please check whether the documentation meets the requirements.
2)Check whether the computer hardware meets the requirements.
Hardware requirements for Teams on a Windows PC.
Note: For Intel processors, the maximum speed achieved using Intel Turbo Boost Technology (Max Turbo Frequency) must be considered
3)Close other applications and clean the client cache.
Delete all files and folders in the %appdata%\Microsoft\Teams directory.
4)Check if the update is the latest version of the client.
