So for a second I missed the fact that according to the GNOME bugreport, this bug is only present in Xorg, not in Wayland. (Michael, can this be the difference between your two computers?)
For me, the behavior with the "Ubuntu on Xorg" choice when logging in is: The terminal icon is shown as the 4th button, using the correct size. However, behind it there's a round button. This round button behind the icon isn't there in Wayland, and isn't there in Xorg with CSD apps [client-side decoration] either. I suddenly couldn't find any other SSD app [server-side decoration] with appmenu that I could check. -- 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-terminal/+bug/1724250/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
