[Bug 1391671] [NEW] Some Unity Launcher Icons Stop Responding in One Screen, Fine in the Other

 

Public bug reported:

I  have two monitors displaying my desktop, and a Unity launcher in
both. I keep some applications in one screen, and some applications in
the other, and some applications (especially chat apps) I drag and drop
between screens depending on what I am working on in that moment.

Every so often (perhaps one or two days in a workweek?), some of the
icons in the left screen (primary) launcher become unresponsive. Other
icons will work fine, but a select 3-4 of them will just not respond.
All launcher icons will work fine in the right (secondary) screen. Today
I just realized that its just my icons that correspond to apps that I
drag around that are doing this (pidgin chat windows, XChat (irc),
sometimes Thunderbird, sometimes Gnome Terminal).

Logging out and logging back in alleviates the issue (which sucks, major
interruption of workflow). I cant seem to reproduce the issue on my own,
any combination of dragging, minimizing, opening, closing, etc, between
different screens all seem to work fine when Im intentionally trying to
recreate this bug. It usually just happens out of no where and I cant
seem to establish a pattern as to when and why.

This is on Ubuntu 14.04 64 bit, and Ive used the same exact hardware /
peripherals for 12.04, 12.10, 13.04, and 13.10. I havent experienced
this issue before 14.04.
