To the extent this issue is caused by im-config setting GTK_IM_MODULE=xim, it ought to be a leftover from ~/.xinputrc files created in 16.04. Since the fix of bug #1605408, nothing should set GTK_IM_MODULE=xim automatically.
I don't understand how uninstalling im-config and then reinstalling it would make a difference. Please note that a change in the im-config configuration needs a relogin to be effective. -- 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
