Okay - I've just discovered the best thing ever if you are testing on a full desktop and using X11 and the guide or an autobump or videos takes over your whole screen and its difficult to get controls back. You can use xephyr to run it all in a nested x-server that acts as a window on your desktop. 

In this picture, the customguide thinks its running in fullscreen, but its really just running in an 800x600 window on my desktop

To enable this, you need to install:

sudo apt install xserver-xephyr
sudo apt install openbox
sudo apt-get install picom


I wrote this script to start it up:

#!/bin/bash

# start Xephyr and wait until the display is actually available
Xephyr :1 -screen 800x600 -ac +extension Composite -glamor &
until DISPLAY=:1 xdpyinfo &>/dev/null; do sleep 0.1; done

# start openbox and wait until a WM is running
DISPLAY=:1 openbox &
until DISPLAY=:1 xprop -root _NET_SUPPORTING_WM_CHECK &>/dev/null; do sleep 0.1; done

DISPLAY=:1 picom &
sleep 0.5

DISPLAY=:1 python3 field_player.py
