Does this happen with my other games/other rpg maker mv games as well or only this one?
So I looked into this, and it seems like this is (most likely) an error that happens due to conflicting settings on your OS. To fix this, you need to change your Windows Display Scaling Settings. You can find tutorials on how to do this online :) Fixing PC Games That Start Zoomed In'' by techoverwrite looked like a good article on this. Hope this helps!
