The problem occurring while running the game with "scale and layout" option adjusting on Windows 10

I set “scale and layout” to 125% while working with maps Landscape Outdoor Terrainв UnrealEngine (4.18). In the editor everything works in a correct way, but when I run the game (no matter where - in a separate window or in the editor window) the coordinates of a mouse click go wrong. In other words, when I click on a place on the map, the click, in fact, takes place far from the initial place. The more I scale, the longer distance from the initial place I get. How can I fix this problem? Thank you in advance!
