When there is an odd number of segments, bevel has an ambiguous choice as to which side face to use to copy face attributes from and to use for UV (and other loops that have math function) interpolation. We used to make choice arbitrarily, which led to visually inconsistent results. Now there is tie-breaking code, face with lexicographic lowest value in vector with these elements: (1) connected component (in math-layer space) id (2) selected (0) vs unselected (1) (3) material index (4,5,6): z,x,y components of face center, in that order.
