In certain circumstances LilyPond will create a very short tie, so short it looks like a dot. Here is an MWE (with a work-around) and I've attached a screenshot:
%%% \version "2.24.4" \paper { ragged-right = ##t indent = 0 } \relative { \voiceOne c''2.^"Modified" r8 r16 \once \override Tie.minimum-length = 3.5 b~ | \break b1 | c2.^"Default" r8 r16 b~ | \break b1 | } %%% This happens in LilyPond 2.25.24 too. Is it worth creating an issue? -- Knute Snortum
