Inconsistent spacing of same-duration notes
If a measure contains longer note values (quarter- and half-notes for example), then shorter notes (8ths, 16ths) in the same measure are spaced more tightly than when the measure contains only shorter note values. This causes same-duration notes to be spaced differently/inconsistently in different measures within the same system.
See how the 16ths are spaced differently in the two measures.
All same-duration notes should have the same horizontal spacing within a system (while obviously taking into account extra space for accidentals and other elements)
The workaround is to carefully manually adjust layout stretch.
This issue's effect is most apparent in situations where tight spacing is needed.
This is probably related to the issue where accidentals and other elements causes unnecessary space to be added to a measure...
