While selecting GTK theme when i get with a light theme.Everything works fine but when I set a Dark theme like nord-darker dracula etc.Then that indicator of what is on focus became invisible.
Is there any dark theme for which it is working fine?
Is there any way to change colour of indication from black to white?
Worst case, GTK3 themes are just CSS. It's possible, although frustrating and time-consuming, to roll your own. In which case you can style *:hover any way you want.
(GTK4, I got nothin'. Last I checked, the development team was going out of its way to break theming. Which is one of the reasons I've been avoiding GTK4 applications.)
