Dear list, My scores are showing blue highlighted translucent backgrounds for musical symbols, particularly when loaded on Ipads. I think it's something to do with each symbol being engraved as a separate glyph? It attempts to externally link to Guile for each symbol or something? When I attempt to 'flatten' the PDF, the problem remains. I'm sure this has been discussed before but I could not find anything in the archives; I must not know what words to use to find this issue. It is not an issue on Windows, or Foxit reader, or Mozilla browser. Performers in the past have turned off a setting that made these highlights go away, but it would be nice for them to not have to deal with it. Lilypond version 2.25.32, Frescobaldi version 3.1.1.
