Jaikoz 12.6 on macOS 26.6, Apple Silicon.
The lowercase “v” glyph is missing throughout the entire UI:
“Save” is displayed as “Sa e”, “Version” loses its v, and filenames
such as “medved” are displayed as “med ed”.
I reset macOS fonts, restarted the Mac, reset Jaikoz preferences,
tested Light and Dark appearance, and tested with
-Dsun.java2d.metal=false. The problem remains.
