In case anyone hasn't solved this yet, I got around the issue by downloading the Borderless Gaming app you can find here:
https://github.com/Codeusa/Borderless-Gaming
And edit the JadeEmpire.ini file in your game's directory and change the following values:
Widescreen=0
ScrW=1500
ScrH=850
Windowed=1
It isn't perfect, and I haven't gotten the values perfectly but it's good enough to play
Don't forget to have Borderless Gaming running while playing the game, and add JadeEmpire to the right side of Borderless Gaming for this to work
