Does anyone happen to know WHICH line in
/usr/share/themes/Breath-Dark/gtk-3.0/gtk.css is responsible for causing Thunderbird's white-on-almost-white misbehaviour like this please?:
Light theme colours do not suffer this bad contrast error:
I have scrolled right through the css, but it is hopeless when i don't know enough of the jargon & concepts underpinning GTK3 theming to be able to find what i need to edit.
Every dark GTK3 theme i have tried, both shipped standard with Manjaro KDE, & also maybe a dozen i downloaded & tested, suffer this identical error. Surely there must be a specific line in that css controlling this?
Note: I probably won't be able to stay at my pc any longer tonight [currently my 21:00], so if anyone does reply please don't be upset if i don't see it & reply til sometime tomorrow my time.
