I'm not sure if the greens are aware but we are getting constant lag, all the champs etc just stutter constantly, if you try to drag a champ or spell across it just lags, even observing games it does the same thing. Its definately not my system as its running fine other than that. Most other people on skype are experiencing the same issues.
ya I had to stop streaming last night because of it, now I can't even start streaming because of it... nobody wants to watch a laggy broadcast.
I got this a lot when I was grinding campaigns, but a restart always fixed it. It also isn't consistent, sometimes it doesn't happen for a long time, sometimes it happens almost immediately. But it never gets better without a restart, so something is definitely going wrong in the client.
