Public bug reported: My wife occasionally shares my computer. After changing users, I've noticed that frequently the Unity panel becomes corrupted. I'm not sure if this is nvidia drivers related or unity related, but I'll open against unity.
I'm attaching a screen-cap of what I see when logging in after another user has been logged in. Sometimes it also affects content of windows as well. https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1625498 looks to be a similar but possibly different issue.
