I have these two problems on two machines as well (both after upgrading to 16.10). One machine exhibits *just* the two symptoms you describe, while another also has an odd bug making the numeric/formula entry text box transparent (see attached).
Interestingly (/frustratingly, confusingly), the menu and transparency issues are not present when running a guest session on that machine, but the menu remains an issue in the guest session on the other machine. ** Attachment added: "20161021-2315-transparent-gnome-calculator.png" https://bugs.launchpad.net/ubuntu/+source/gnome-calculator/+bug/1615408/+attachment/4766645/+files/20161021-2315-transparent-gnome-calculator.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1615408 Title: Theming issues with yakkety gnome-calculator in Unity To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-calculator/+bug/1615408/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
