This bug has a long history in Chrome of appearing several times, as well as being
fixed several times. Turning off hardware acceleration sometimes fixes it,
but perhaps only incidentally because it restarts Chrome.
Reinstalling Chrome sometimes also helped momentarily.
It was last "fixed" in version 34.0.1838.2 :
Issue 341879: REGRESSION: Status bar/bubble and tooltips no longer appear,
but was observed to be triggered again when any drop-down list was used.
Issue 345698: REGRESSION: URL Not Displaying in Lower-Left Corner When Hovering Over Link
in which the latest entry from 2014-03-11 seems to promise a final solution.
The issue is marked as Closed on Mars 10.
I suggest waiting for these fixes to find their way into the official version.
Better keep an eye on Issue 345698 and relaunch it if necessary.
The bug has to be fixed in Chrome itself, as there is no workaround possible for it
except restarting Chrome.
It should be noted that this is not one bug that reappears again and again,
but rather multiple bugs having the same effect.
There is no guarantee that the bugs fixed in
Issues 345698 and 341879 are the last of their kind.
