Actually there is more, as it's shown on this other video. The same problem happens when “there is a display event”…? Like when my mouse go over an element, even if I can't click on it.

I already had a display problem once, so I knew it was better with a external video. + + EDIT: I remember having this problem a year ago perhaps, and it + disappear if I reboot my computer.
