This bug has been opened here: http://bugzilla.ubuntu.com/show_bug.cgi?id=17137

"With the new transparency for the window list, there is a draw bug if the window
list is aligned at the bottom of the screen. Occasionally, when all windows are
minimized and the panel is transparent and at the bottom, a black artifact
appears after the last button on the list.

other similar bug; http://bugzilla.ubuntu.com/show_bug.cgi?id=17237

"I was complaining in bug 17056 that the window list in the bottom panel had
recently become transparent, but I was told that this is a new feature, not a bug.

So I left it transparent, and started to notice that the wallpaper I could see
through the window list was getting messed up.  I couldn't see exactly how, so I
wrote the alphabet twice across the bottom on my wallpaper so I could see more
clearly what was happening.

See the attached image.  The top strip shows the bottom panel before I open any
windows.  You can see the alphabet on my wallpaper showing through.  The bottom
strip shows the bottom panel after I've opened a bunch of windows and closed
some of them.  Notice how the letters from o through to z on the far right have
been replaced by c through to m.

If I point the mouse at the corrupted area, the window name I point to goes
non-transparent, but when I move the mouse away, the corrupted image returns.

Even if I click in a corrupted area, the window name goes non-transparent, but
again the corruption returns when I select a different window.

If I use the 'hide buttons' on either end, then the wallpaper is revealed,
showing 2 complete alphabets again, and when I un-hide the panel, the correct,
uncorrupted alphabets are now shown.

I've seen this a few times now, but don't know exactly how to reproduce it.  It
certainly happens without me moving anything on the panel.  I didn't move
anything, or add anything or remove anything from the panel.  All I did was run
programs, switch between programs and stop programs.

a pair of screenshots showing the problem

notice how the letters are different on the right-hand edge in the two panels"

I'd say this is a bug in the applet, not in libwnck. Moving to gnome-panel.

This is actually a symptom of bug 167771.
