After some googling around, in the end I ended up doing this: sudo apt install gnome-calculator sudo snap remove gnome-calculator
And now both my keyboard calculator shortcut works as well as the calculator is no longer transparent. I have no idea what snap even is. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-calculator in Ubuntu. https://bugs.launchpad.net/bugs/1767541 Title: Transparent background of calculator in ubuntu 18.04 using communitheme To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-calculator/+bug/1767541/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
