I would start enabling the debug messages, it should give you good hints
on how things work. For instance, with spicy --spice-debug:
/* Resizing the widget */
GSpice-DEBUG: spice-widget.c:1228 recalc geom monitor: 0:0, guest +0+0:640x480, window 714x522, zoom 1
GSpice-DEBUG: spice-widget.c:1228 recalc geom monitor: 0:0, guest +0+0:640x480, window 715x524, zoom 1
GSpice-DEBUG: spice-widget.c:1228 recalc geom monitor: 0:0, guest +0+0:640x480, window 716x525, zoom 1
(...)
GSpice-DEBUG: spice-widget.c:1810 focus_in_event
GSpice-DEBUG: spice-widget.c:1462 release_keys
GSpice-DEBUG: spice-gtk-session.c:203 inputs-3:0: client_modifiers:0x2, guest_modifiers:0x2
/* Sending new monitors config! */
GSpice-DEBUG: channel-main.c:1118 main-1:0: sending new monitors config to guest
GSpice-DEBUG: channel-main.c:1135 main-1:0: monitor #0: 716x525+0+0 @ 32 bpp
GSpice-DEBUG: channel-main.c:1070 #0 +0+0-716x525
GSpice-DEBUG: channel-display.c:1820 display-2:0: received empty monitor config
GSpice-DEBUG: channel-display.c:1820 display-2:0: received empty monitor config
GSpice-DEBUG: channel-display.c:1820 display-2:0: received empty monitor config
GSpice-DEBUG: channel-display.c:1820 display-2:0: received empty monitor config
/* Done with the interesting part */
Very likely it should be possible to improve the spicy testing tool to
have something that could you help you test it, like some text fields to
set display X width X height values.

You will then need to hexdump the data and start trying to get the
meaning out of it. I think it is more interesting to include more debug
in the agents if you want to know more specific details about something
that is going on. Or even gdb -p $PID.

Feel free to ask your doubts here as well. We would gladly take any
patches that improve the documentation/testing tools too :)
