Bug Description
Binary package hint: lubuntu-artwork
SRU :
1. This bug impact all Lubuntu users using the theme by default, increasing the CPU usage for all applications. It's more visible on limited hardware, which is the target of Lubuntu.
2. This bug was fixed on 0.15 version of lubuntu-artwork. The animation setting was turn off (it's also the case for Ubuntu theme).
3. The patch is available on bzr branch of lubuntu-artwork for Natty (http://
4. You can reproduce the bug by launching lxtask. You should have an increase of the CPU usage on Xorg and on lxtask itself.
5. The only regression I'm aware is the removal of animation of the progress bar. But as Ubuntu don't use this type of settings, I think it's quite safe to turning it off. I also used it during a week, without any problems.
I noticed an increase of the CPU usage when using lxtask, and the new gtk theme is Lubuntu 11.04. There is ~ + 20 % of CPU usage between the old gtk theme and the new one, using a 1 Ghz CPU. I still don't know if it's the theme itself, or the use of murrine + cairo on my machine which is problematic.
Using a eeePC 701, Intel driver.

I don't really know (for now). But using a task / process manager increases the CPU usage a lot, because of the continuous scanning of threads in RAM. Try gnome-system- monitor and you'll see your CPU usage increasing up to 100%. If problem persists without using monitors the it's another problem. The theme was tested (a lot) for checking its resources hungry and it must be as fast as any other Cairo based theme (like Elementary or Deepin).
Anyway I'll keep it an eye.
