Public bug reported:
I've found that taskbar plugin doesn't update window titles unless
there's a desktop switcher added in some of the panels. For example, all
browser windows are shown as "Mozilla Firefox" (instead of each web
title), and all PcManFm are shown as just "PcManFm" (instead of current
directory name). Also, behaviour of the setting "Show only windows in
current monitor" (sorry if this is not the right spelling, I use Lubuntu
in a non-english language) is erratic at best.
Adding a desktop switcher to any panel solves the problem. It seems to
me that lxpanel assumes that desktop switcher is the only plugin who
needs window info updates, so, when no desktop switcher is shown, it
stops sending it to the plugins. Problem is that taskbar plugin needs
this info too, and it stops working right.
