          Severity: minor
    Classification: Unclassified
                OS: Linux (All)
          Reporter: sduchesne at gmail.com

           Version: 1.12.6
         Component: xlib backend

cairo produces a black background (overriding the gnome wallpaper) in the
Activities overview in gnome-shell  using the proprietary AMD Catalyst fglrx
driver.

System information:
Arch Linux, kernel 3.6.4-1
X.Org X Server 1.13.0 
cairo 1.12.6-2
gnome-shell 3.6.1
GPU AMD Radeon HD 6450 running catalyst-utils 12.9-0.1


Workarounds:
- Rolling back to cairo 1.12.2-3 fixes the problem using the AMD Catalyst
driver.
- Bug can not be reproduced using cairo 1.12.6-2 with the open-source ati
driver (1:6.14.6-2).
