Adjusting 'staff-space sometimes results in wrongly placed note-heads.
Minimal example:
\version "2.17.17"
{
\override Score.StaffSymbol #'staff-space = #(magstep -3)
<g b d'>
}
Some observations:
{
% Minimale adjustment works:
\override Score.StaffSymbol #'staff-space = #(magstep -3.0000000000001)
<g b d'>
}
{
% Calculated but too exact (?) value of (magstep -3) doesn't work
\override Score.StaffSymbol #'staff-space =
#0.70710678118654752440084436210485
<g b d'>
}
{
% Calculated _and_ rounded value of (magstep -3) works
\override Score.StaffSymbol #'staff-space = #0.707106781186548
<g b d'>
}
Other problematic values: -16, -15, -14, -9, -3, 3, 4, 9, 14, 15
Cheers,
Harm
