Open attached file (created in 2.x). The lyrics have been appended at the end of the score in 2 x 2-column vertical frames. But, in 3.x, the right-hand columns have lost their horizontal offset and now coincide with the left-hand columns.
(There is also a problem with the font-size of a verse in the second frame, which is smaller than the rest)
