The root cause is because the offset used in DxgiOutputDuplicator should always depend on the position of the monitor in the system instead of the offset in the target frame. Otherwise, once switching between two monitors with different screen size, the updated region in the context would base on the old monitor, and cause the copied regions to be out of the source DesktopFrame. This issue also impacts the SpreadContextChange() function, the updated region stores in the Context should also only depend on the position of the monitor.

WebRTC is a free, open software project that provides browsers and mobile applications with Real-Time Communications (RTC) capabilities via simple APIs. The WebRTC components have been optimized to best serve this purpose.
Our mission: To enable rich, high-quality RTC applications to be developed for the browser, mobile platforms, and IoT devices, and allow them all to communicate via a common set of protocols.
The WebRTC initiative is a project supported by Google, Mozilla and Opera, amongst others.
Development
See http://www.webrtc.org/native-code/development for instructions on how to get started developing with the native code.
