A bit more information on this bug. It appears this only happens when "Mirror screens" is enabled - which is the default behaviour. So anytime you plugin a new external display or change an existing display to mirror screens you can trigger this bug. I didn't see it on my external monitor on my desk because it was setup as an extended screen.
