stream-channel: Do not show an empty blank screen on start

Browse Source 
Start showing something when we have a surface and stream
instead of showing a blank screen which is now not useful.
Was useful for debugging purposes to understand that the
new channel was sending messages correctly to client and
client could handle them.
