Surface 3 Tablet touch mode not working (Steam Version)

Firstly thanks for creating a great game!

I have a Surface 3 tablet (the i5 version) that i am using while traveling and have been playing GDT on it. However the touch screen doesn’t work correctly. It feels like the touch is being offset by a few inches whenever i try to click on the screen.

Has anyone else had this problem and if so how do i get it working?

The screen res of the Surface 3 is 1920x1280 (landscape) or 1280x1920 (portrat).
Touch screen doesn’t work correctly in either full screen or windowed mode. The echo of where i touch the screen shows in the right place but GDT seems to read that and then offset it.

I have only tested with the steam version. I would like to keep this version as all my progress is on that one but if it works fine on a different version i amd happy to buy that.

Thanks for the help guys!
