First I thought Dispatch is great (edit: still think it's great ;) ) and has much less connection issues then Kiwi IRC or The Lounge here on this really bad internet connection...

But then I noticed it just fails less obviously (and probably also a bit less often :) ). Tell tales signs are usually duplicated messages, strangely distorted fonts and bleeding through of messages into other channels.

Not sure what can be done about it, but maybe some overlay with "connection issues" would be a start?
