Title:
  Xorg uses lots of CPU when a Gtk2 widget has a background image

Status in “gtk+2.0” package in Ubuntu:
  Confirmed

Bug description:
  This problem was first reported against GCstar, but it's not specific
  to that application.

  Since they upgraded to Ubuntu 11.10, many users reported that the
  application is really slow. After some investigations, it appeared
  that the problem occurs when the application uses a background image.
  It was only reported for Ubuntu and doesn't seem to affect other
  distributions.

  I managed to create a small script that shows this problem. Its only
  dependency is libgtk2-perl. After it's started, Xorg is using a lots
  of CPU and the whole system is less responsive. This script is
  attached to this report.
