When my pair stops screen sharing, and my screen-share window was full screen, the video display is left full screen. The large video is jarring, but moreover, it makes it difficult to share my screen, since the active workspace is the full-screen video of my pair. To share the workspace I want to share, I have to un-fullscreen the window, and then share. Swapping drivers would be more fluid if ending the screen share returned to a non full screen state.
