The 7-to-8 issue is a problem with unity8. I've got a branch attached. I don't know what's going on with your 8-to-7 issue, but I can't reproduce it myself.
I don't actually recognize what's going on with your screen in that video -- you have an OSK? With some white box in the middle of the screen? ** Package changed: lightdm (Ubuntu) => unity8 (Ubuntu) ** Changed in: unity8 (Ubuntu) Status: New => In Progress -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1604374 Title: Lock screen/greeter shown when switching user sessions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/unity8/+bug/1604374/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
