In reply to Henrik.

@Henrik: Thanks for your feedback. When video is not available for a user, their avatar will bedisplayed in its place in the active speaker window/thumbnails. You can use Floating Panel View to minimize the active speaker panel when content is being shared.

We are working on optimizing the remote control experience in an upcoming release, so stay tuned! In the meantime, to get around this, you can simply change views and/or adjust the zoom accordingly when controlling a remote desktop.
