Hey,
I just noticed a thing.
A client apparently consumes bandwidth from the server although the client is clearly muted and nothing should be sent.
A small example can be seen here on the picture:

Is that supposed to be the case? If so, why and how can I prevent this?
If not: Is the bug already known or should I report it as a bug?

Thanks
