No issue on Linux (gtk3, gen, kf5) but reproduced on Windows. Changing the notes background to white is necessary. Side note: changing the presentation style Notes has no effect on Windows but works well on Linux (setting the Area per DF works on both OS).

Resolved with https://gerrit.libreoffice.org/c/core/+/158024 (new contrast applies to all colors but Light Blue 2 aka Tango Sky, which is the default for object background).
