I am the research and development of Tencent Conference. Our users reported that using the magnification api to capture the extended screen will capture black frames, but the main screen will not capture black frames. Users reported that there were no black frames before updating KB5027223 and KB5027231, . After updating KB5027223 and KB5027231 A black frame appears.
