It appears that the xinput devices(keyboard/mouse) are being hijacked by
desktop? As long as there is user input(keyboard/mouse activity) at
least once second within Sauerbraten, everything works as expected in
Ubuntu 18.10. Further bug info: I noticed that if you're moving forward
with the 'w'
A little more info:
_As soon as_ you switch sauerbraten(multiverse package) to
fullscreen(Step 3, above) in Ubuntu 18.10, the system mouse pointer
