Annoying & distracting pop-up (containing mostly redundant info)

view story

http://ubuntuforums.org – Hello, I have something new for which multiple searches have provided no clue. I have this annoying black pop-up with white text, which will sometimes post the first few lines of a post, but most of the time only repeat what is already on display. This is NOT restricted to the browser, but appears to be OS-based (Lubuntu in my case) The annoying thing appears in ANY window, if the cursor has been stationary for a few seconds. In file manager if the cursor is on a file icon, it will pop-up and contain the file name which also is evident under the icon. This nasty annoying thing is distractin (Hardware)
