Unable to play on any resolution other than native

I bought the Legacy Collection, but the neighborhood screen seemed far too small, and the UI was really tiny and the game was too zoomed out. So I changed my computer's screen resolution to 800x600 only for this to happen when I open the game. Sorry for the camera recording, for some reason this glitch wouldn't show up in screenshots. Also, ignore the Blue Line in the top left corner of the screen. That's a monitor issue, and unrelated to the game. Any and all help is appreciated.
