Bug Description
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.

I cannot reproduce this myself but does this happen if you don't use the nvidia binary drivers. Although can't use novueau with 900 hundreds series. I could not reproduce this on my intel graphics desktop or in a virtual machine. Although not sure if your processor has onboard graphics or if it works with noveau. Also you meantion settings for multiple monitors does the same thing happen when you only have one monitor active?
