Right, details:
<DETAILS>
OS: both are on Xubuntu 13.04 (although, after my server update, when it 
boots it says Kubuntu......)

Network: Wired through Cisco router.

Cmds: Server: xpra start :100 --no-daemon   Client: xpra attach 
ssh:user at host:100

Xpra info:
$ xpra info :100

Is it reproducable? I don't know. I can reproduce it on my system, but I 
don't know what's broke on it.....
</DETAILS>

The ugliness may be due to theme setting on the server. I'll see if I 
can connect from the server to the client and see if it is any better 
and from my laptop to one or both of the two and see how that works.

The mouse only seems to work correctly on one of the monitors on my 
client (I have 4 setup in a square). If the server app isn't on my main 
screen, the mouse only moves windows around (which is client-side, 
anyway, if I understand it correctly). That's probably an xorg.conf 
issue, but I don't know enough about configuring xorg to figure that out....

I hope that helps, let me know if you need more info.
