[Bug 1351982] [NEW] top panel and launcher are unresponsive

 

Public bug reported:

Unity has recently (~2014-07-15) started exhibiting two odd behaviors that are likely related:
1) The launcher, which is set to autohide, will appear and disappear in <1s (even though I hover over the launcher). It is unresponsive to clicks.
2) All applets  in the top panel are unresponsive to clicks.

1 & 2 always occur together at some point during a session. That is,
these components work correctly for hours (days?), then become
unresponsive. I have not yet identified the trigger event; screenlocking
or suspend/resume *may* be related, but not reliably so (i.e., I can't
reproduce it this way).

Restarting unity-panel-service (killall unity-panel-service) doesn't
help. The problem is temporarily fixed by logging out/in or rebooting,
but the issue recurs.

The timing of the first occurrence (in July) is probably consistent with
my first use of unity-tweak-tool to set focus follows mouse, although
this hypothesis doesn't explain why the components initially work and
then become unresponsive. Otherwise, my config is pretty stock.
