Hi Gilberto,

There is no checking for straight flags, the beam lengths are just taken
from
Stem.details.lenghts (optimised for ordinary flags).

Looking into Stem.details.lengths, the entry for 32th flags is 4.25. That's
why the flags are being placed in between stave-lines.
If you set this value to 4.5 (or to 4.0 if you prefer shorter stems), the
flat-flags will work as expected:

The modified Stem details are:

  \override Stem.details = #'((lengths 3.5 3.5 3.5 4.5 5.0 6.0)
                              (beamed-lengths 4.26 4.5 4.6)
                              (beamed-minimum-free-lengths 2.83 2.5 2.25)
                              (beamed-extreme-minimum-free-lengths 2.0 1.25)
                              (stem-shorten 1.0 0.5 0.25))

HTH,
Torsten
