Re: staffSize music function unreliable at LP v2.19.16
Hello, a possible workaround would be to insert \layout { \context { \Voice \override Stem.neutral-direction = #'() \consists Melody_engraver } } It computes the stem direction for neutral-position (i.e. normally the center staff line) and here also the wrongly flipped f’s such as to suit the surrounding notes.

I should add that the original code was missing a right closing brace after \staffSize #2 to close off the \with block.

I wouldn't know how to build LilyPond for Windows to verify any fix... An observation. In the following snippet, you'll note in the log output that the default-direction of the downstemmed F and B is 0--CENTER. This means that Stem::calc-direction (in lily/stem.cc) will take the property 'neutral-direction. This property is supposed to specify the direction of a note on the midline--B only in our case. F should have a default-direction of 1. Note that adding \override Stem.neutral-direction = #1 fixes the problem for the bad stems.
