Setting the bug back to confirmed since the issue seems not to be fixed.
The attached screen-shot has been taken directly after login into Lucid the 20th of April.

I can confirm this on a fresh install of Lucid final. Occurs with radiance as well.

This seems to be a problem with the panel or the applet itself. Moving the window list seperator and then moving it back makes the white line go away.

I'm currently using Ambiance, the default theme in Lucid, and I've noticed the following behaviour.

When I get the white line, I can make it go away by going to System > Preferences > Appearance, change to another theme (e.g. Clearlooks), and then change back. When the panel goes back to Ambiance, it does so without the white line.

But if, instead, I simply try to do
$ killall gnome-panel
the white line does not go away when the panel reloads.

I imagine #6 is faster than my method if someone just wants a quick workaround to make the white line to go away, but hopefully the information I've provided might be of some use in finding a solution.

Hmm, today when I booted into lucid, gnome loaded with both bug #439448 and this one. I ran "killall gnome-panel" to workaround the other bug and, to my surprise, the white bar also went away shortly after. This made me curious and I've tried to experiment a bit with this. First, I think the fact that bug #439448 was present was just a coincidence. Here's the results I've been seeing...

When running killall gnome-panel, one of 2 things happen:
1. The panel loads with no white bar
2. The panel loads with a white bar, but if I open a new window or close a window, the white bar goes away when the list of open windows in the panel changes

What's interesting is when I keep running this command over and over, sometimes the panel even goes from no white bar to having the white bar. When I have the white bar, I can either keep running the command until it goes away or I can just open or close a window.

I have a feeling that when the panel loads, there is a chance that the white bar will appear due to some race condition, but I'm working on limited knowledge here. I'm just a user and I have no idea what's going on underneath the hood. Now, another thing that's interesting though is that if lucid originally boots with the white bar, opening or closing a window doesn't seem to make it go away unless I run the command first at least once.

So, it seems that actually, even if I don't run "killall gnome-panel", the white bar tends to eventually go away. Maybe the chance of the white bar appearing (or not appearing) happens every time the panel changes? I wonder if the white bar can randomly appear after the panel being drawn without it, just by causing the panel to redraw enough times?

theme problem continues.

Yes, this problem still regularly occurs in Maverick. It seems random; I cannot replicate it, but if you move or reload the icon it goes away. Obvious visual discrepancies like this are as puzzling as they are annoying.

For me the white bar appears sometimes when I log in and when this happens it always disappears when I open 2 windows, so that the bottom panel's "Window List" has two entries.
