Hi,
I'm using Ubuntu MATE with the materia theme.
KeepassXC show some green buttons, unlike other QT apps which seem to inherit the GTK . It seems older issues like https://github.com/keepassxreboot/keepassxc/issues/1931 aren't relevant for this case, as they implemented a new view:
https://github.com/keepassxreboot/keepassxc/pull/4910
But I'm wondering where the green buttons are coming from.
