It seems the latest update (Version 2.0.99.113) broke UI scaling when using a controller.
When I started playing I set the UI scaling to the lowest value (0.7 I believe) and it was working fine yesterday with a controller (PS4 dualshock). However, after the update, when starting the game today I noticed the UI was extremely big and when I went to the options menu to change it back, the scaling option under the "Game" settings had disappeared!!
I disabled the controller, went back to keyboard+mouse and sure enough, the UI scaling option is there.
