Similar effect here, running Kubuntu 11.04, cssh 4.00_05, Tk 804.029, X11::Protocol 0.56
In addition, I tried to set the terminal_size to 80x5, but only the first of the xterms uses that.
All others are 80x24 - not practical when you need to treat 32 hosts at a time.

(HOw do I add a followup to this? Only option seems to be Edit this text...)

I think I remember this discussion revolving around the fact that KDE is controlling the window decorations and that information is not available to tk/tcl when tiling the windows. Just found this https://sourceforge.net/p/clusterssh/mailman/message/265939/ which discusses tiling issues. I am now using terminal_reserve_top=25 and the windows tile file. I am assuming that this ticket is really old and not a problem anymore. Anyone else?
