Thanks for letting me know! That'll be fixed in the next patch. For now, changing your resolution to anything else and back before swapping fullscreen mode will prevent the bug.

Oh gosh, I see the issue! You'll need to delete the persistent game files as it's saving your 'preferred resolution'. (a save system is in early development).
- Go to C:\Users\<user>\AppData\LocalLow\Cuttledile
- (if you copy-paste that you'll need to fill in <user>)
- delete the whole WelcomeToTheEmbassy folder
Thanks for your patience with this!
