I can reproduce the problem with plenty of other names taken from the Humanity theme, such as "clock" or "gnome-panel-force-quit" instead of gnome-terminal's default "utilities-terminal".
The culprit really seems to be gnome-shell/mutter, or some library used by them. So far I could only reproduce the problem with the Humanity icon theme, although I haven't really tried other themes (only Adwaita a bit). It could even be that the icon theme ships something wrong. The problem is present both with the "Ubuntu on Xorg" (Ubuntu flavor of gnome-shell experience) as well as "GNOME on Xorg" (default GNOME experience), provided that I switch the latter using gnome-tweak-tool to use the Humanity icon theme. ** Also affects: gnome-shell (Ubuntu) Importance: Undecided Status: New ** Also affects: mutter (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-terminal in Ubuntu. https://bugs.launchpad.net/bugs/1724250 Title: gnome-terminal graphic artifact To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1724250/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
