Incorrect scale bar values in the 2D View

The scale bar in the 2D view reports ~50 meters for a 100-meter scaled Cube mesh from /Engine/BasichShapes (the size of the Cube is 1 x 1 x 1 meter).

UE 4.26.2

I found the reason of this - I am using a 4K display and in the UHD mode the scalebar shows incorrect value, whereas in FHD the value is correct. Maybe this is also linked with the font resolution in UHD, which is 225% in my case.

The Measure tool (Middlemouse + drag) shows correct values in both UHD/FHD modes.
