I found that this bug only applies when using any of the pre-defined Panel Layouts: Cupertino, Fedora, Redmond, etc. When I use the default Ubuntu Mate Panel Layout there is no issue.
I'm running Ubuntu Mate 16.04
I agree with other users that I think it has to do with the window border pixel range.
