I use Ubuntu 12.04 with gnome-shell and default Ambiance window theme. There is a display glitch on title bar of background windows. It can be seen on the screenshot below.

The bug also occurs with with Radiance window theme, and also when I use gnome-classic.

I must have messed with some configuration file on my home directory because this problem doesn't occur with another account (guest account in fact).

What can I do to simply get rid of this annoying display glitch ?

Welcome to AskUbuntu. Have you try this ?. What is your gnome version? – penreturns Oct 6 '12 at 20:23
Thank you for your answer. The instructions provided by your link did not change anything. I use version 3.4.1 of gnome-shell. – Jean-Louis Jouannic Oct 7 '12 at 12:50
