This issue is not new: it was there in MS 2.3.2.

  1. Open the attached file. Observe the vertical placement of arpeggio symbols.
    Expected result: The arpeggios are well vertically-centered on the chords.
    Actual result: The arpeggios are asymmetric.

  2. Click on the top note in the second chord and move it upwards, step by step, noting the vertical placement of the arpeggio.
    Expected result: The arpeggio is well vertically-centred.
    Actual result: The vertical centering seems to vary according to the interval between the bottom and top note.

Suggestion: The default vertical placement of an arpeggio needs to be as symmetric as possible in relation to the top and bottom notes of the chord.

I suspect the issue here is that we draw these by gluing together multiple copies of a very specific shape, and we have a choice of using N or N+1 copies. In some cases N might be too short, N+1 to long. We could consider slightly scaling them, or using a half-shape. This is one that @oktophonie should probably weigh in on. Perhaps the solution is as simple as using a slightly smaller glyph to there is less difference between N and N+1, and perhaps the new notation font being designed could do this. Or, maybe we always go with N+1, but then shift upward slightly to center better, if indeed that's a reasonable goal (Gould doesn't seem to say specifically).
