Please bare with me here, because this might not be the right way to do this, but changing the background-image size and the margin seems to look good here.
I haven't generated new PNG's, so they are stretched from 20px to 22px. ** Attachment added: "gtk-widgets.css" https://bugs.launchpad.net/ubuntu/+source/ubuntu-themes/+bug/1693609/+attachment/5107363/+files/gtk-widgets.css -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ubuntu-themes in Ubuntu. https://bugs.launchpad.net/bugs/1693609 Title: The "Minimize", " Maximize" and "Close" buttons are too small to click Status in Ubuntu UX: Confirmed Status in ubuntu-themes package in Ubuntu: Triaged Bug description: The window control buttons ( _ 🗖 X ) in Ambiance are noticeably smaller than other icon buttons in the headerbar of a "native" GNOME3 app. I think this is both a visual issue and an accessibility issue since it is harder to click the window control buttons than the other buttons. Please compare with Adwaita which has a much larger click area for the window control buttons. Commentary ---------- Remember that one of the major strengths of GNOME 3 is that it is usable on a touch-enabled laptop. And while there are many people that complain about Adwaita, I believe many more actually like the proportions and padding of the default GNOME theme! ubuntu-themes 16.10+17.10.20170518-0ubuntu1 Ubuntu 17.10 Alpha To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-ux/+bug/1693609/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : firstname.lastname@example.org Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
