[Bug][1.0B2]Blank mainchat screen

[Delta-Z 0]

If all of the following:

- minimize at program startup

- configured to connect to hub on startup

- that hub sends more than a screenfull of text on connect

Then the main chat screen contents for that hub are not drawn (no text) when I restore the application from tray. After any operation that leads to redraw (scroll/resize/chat) all the text is shown correctly.

Not a big one but annoying since those are exactly the settings of my home hub.

Probably related to this one: Hub windows empty
