Did some more testing - Running the setting change that I made in my first post (DPI setting override) at 1920x1080, then changing the setting for "Game Area Size" to Large sets it to widesceen on my PC. Try this and let me know if it makes it any better - otherwise we might have to see if we can get Jeff in on this and see why resolutions higher than 1080p have a hard time using the full screen.

You said your default resolution is 3840x2160 - I would recommend down-scaling the resolution on your laptop either in-game or with the box that pops up prior to the game launching (not sure how this works with Steam). According to https://bneijt.nl/pr/resolution-scale-calculator/, you have a few options. You can start with 2560x1440, or try 1920x1080 (this is what I'm running). Try it and let me know!

Earlier today I downloaded the demo and was having the same issue. After playing around with my settings, I found a solution: Right-Click on your "Avernum 3" desktop icon, select properties, and go to the "Compatibility" tab. In here, check the box next to "Override high DPI scaling behavior. Scaling performed by: Application". Save and close the box. Now run the game and see if it fixes the problem. It will show the box in the widescreen, rather than it being fit to the size of your screen - this is because the game is trying to upscale the box to match the size of your screen, which causes the overlap. Hopefully Spiderweb will come out with a way to fix this permanently and stretch to scale widescreens instead of upscaling the standard resolution.
