Turns out I can't change my display's resolution for a specific app unless I do some commands here and there
I did try the standard 16:9 aspect ratio and the cropping problem went away!
2560x1600 (16:10): Can't see the Enter button 
2560x1440 (16:9): Enter button is back!
I suggest adding a resolution setting in the Graphics settings so the user can simply choose a resolution, but if it complicates things. Then yeah just add the 16:10 aspect ratio, or just have the game force the display to view the game in the standard 16:9 aspect ratio. There are likely a bunch of other ways, those are what I could think of.
And don't worry, 16:10 is a relatively new aspect ratio that gaming laptops are starting to use. Games are steadily starting to adapt to that new ratio so you're not the only one with this problem
