I experienced this bug today. Restart didn't help initially. Then I changed the Input Method from xim to ibus and the problem was gone. Changing back to xim did not bring the problem back. I'm confused that it worked. Would be nice if somebody else could try the same.
I did not install any new packages, neither did I re-install any packages. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1760818 Title: gedit and gnome-calculator transparency/graphics corruption issue To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/im-config/+bug/1760818/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
