[Bug 47295] Corrupted dialogue buttons

[Mark W. Tomlinson]

Public bug reported:

Binary package hint: libgtk2.0-0

(NOTE: I'm assuming libgtk2.0-0 is providing the button widgets.)

After installing the Dapper RC (Alternate) on my laptop (Sony VAIO PCG-
GRZ610), I opened update-manager in response to the "updates available"
balloon.  I immediately noticed that the "Help" and "Close" buttons were
corrupted by a series of vertical lines of dots (I'm going to upload a
screenshot).  As soon as I moved the pointer over the buttons (just
hover, no click), the corruption disappeared.

This behavior occurs in just about any dialogue that offers action
buttons to a greater or lesser degree.  I just brought up "About GNOME"
and the "Close" button has a horizontal series of dots across the
bottom, which go away as soon as I point to it.

I'm running the "out-of-the-box" xorg configuration, which selected the
"ati" display driver.  Please note that I do not see this behavior on my
desktop (nvidia-glx).

As stated earlier, I will upload the screenshot from the initial
observation.  Please let me know what additional information might be
helpful.

** Affects: gtk+2.0 (Ubuntu)
