Description Sebastien Bacher 2005-08-18 22:09:38 UTC 
This bug has been opened here: http://bugzilla.ubuntu.com/show_bug.cgi?id=13770

"These are the steps I take to produce this bug:

1. Set application font to "Bitstream Vera Sans (Roman)" size 8.
2. Open the desktop background selector.
3. Click on the button to display the color picker.
4. Leave the mouse pointer over the "Color Name" label/box long enough for the
tooltip to appear.

Once the tooltip appears it does not vanish until the color picker window is
forced to close with Metacity.

I forgot to mention that I'm using Ubuntu Breezy Badger Colony 3."

That happens with gtk-demo from GTK 2.8.0 too.
