When using chromium browser, for a while, suddenly a new blank white rectangle (its sizes is not a fixed value, sometimes it has the size of an icon and sometimes a large window) appears and sticks to desktop on top of everything.
Can't get rid of it unless a Unity reset is performed or a logout.

Please see screenshot.

It usually appears at the top left corner of the screen.

Same bug appears when using Google Chrome.

Using UNity 5.8.0 on precise - amd65.
