I don't think it's a Gnome issue per se.  I saw this occasionally under LXDE and still today under XFCE.   I primarily see it in
Thunderbird and Firefox (typically in the Tab headings) and it normally clears when I click on the tab.  Perhaps what I'm seeing is
something peculiar to some extension I have in Thunderbird and/or Firefox.  I don't know for sure.  It's never bothered me enough to
try to determine what is happening since it clears when I "refresh" the tab.
