--- Comment #8 from Mattia <alterme...@gmail.com> --- At the moment I've added this to my ~/.config/gtk-3.0/gtk.css and it works for GTK3: decoration, headerbar.titlebar { border-radius: 0; box-shadow: none; margin: 0; } I guess the same will work with GTK4. In any case, this is something that the user needs to do – I don't think KDE should change the CSS for GTK apps. Nevertheless, I don't feel like this issue is enough to not implement noborderrule=2 altogether. -- You are receiving this mail because: You are watching all bug changes.
