[winswitch] client side window is too tall and wide

[Tim]

 Here is the command output when running Xpra client on  C55dt-a  (display  size 15.6") to connect to Xpra server on T400 (display size 14.1"). Both runs Lubuntu 18.04 with LXDE and OpenBox and latest Xpra version. The client window on C55dt-a has no scrollbar and resize in the window's menu is disabled. (When I run Xpra client on T400 to connect to Xpra server on C55dt-a,  same problem: the client window also has no scrollbar and resize in the window's menu is also disabled.)

$ xpra shadow ssh:"$remote":0

Hi,I am using xpra between two Lubuntu 18.04. The two laptops have different screen sizes: Thinkpad T400 with smaller display, and Toshiba satellite c55dt-a with bigger display.
When running xpra client on T400 to access xpra server on C55dt-a, the client window is smaller than T400 display in both height and width.
When doing the opposite, the client window on C55dt-a is bigger than C55dt-a display in both height and width.  I can resize it, and although I can move it from side to side, I can't move it from up to down, so I miss some part down below. I was wondering how I can solve the problem?
Thanks.
