Comment 3 for bug 965080

A replacement would be a checkbox like:

 [x] Avoid my mouse cursor to be accidentally lost in another display

But I'm afraid that it's rather long, and anyway this setting is too "advanced" to be shown in the place where it is. And note that I don't fully understand the purpose of the "Sticky Edges" and what problem is solving, so take the above checkbox only as an idea of a self-explaining setting.
