Title:
Xorg uses lots of CPU when a Gtk2 widget has a background image
Status in “gtk+2.0” package in Ubuntu:
Fix Released
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.
