On both layouts the scale bar widget is working properly. The
distances (and areas) are properly calculated in QGIS interface. I
have set the GRS 1980 ellipsoid for distance and area calculations.
What does it mean to use a geographic CRS for a print layout? Do you
really expect longitude on the x axis and latitude on the y axis? The
value of meters/degree is different for x and y, unless you are at or
near the equator. (Living at 42N-ish, I'm very aware of this.)
This may be the case for projections like EPSG:3857 that are based on a
spherical projection of the Earth but is it the case for all projections?
