Details

Description:

Running "display" application from imagemagic package to set root window wallpaper causes high CPU load in both display and X.org processes. display at 20-30% CPU and X.org ~90% CPU.
If left running will cause gfx driver to crash, both nouveau and NVIDIA proprietary become unstable and suffer GPU lockup in the extreme case.

As of reporting this both 2 latest imagemagic packages cause the issue. Downgrading to "imagemagick 6.8.2.3-1" resolves the issue.


Additional info:
* package version(s)

imagemagick 6.8.3.10-1
imagemagick 6.8.3.9-1
nvidia 313.26-2
mesa-libgl 9.1.1-1
nouveau-dri 9.1.1-1
linux 3.8.4-1
xorg-server 1.14.0-2
fluxbox 1.3.5-1

* config and/or log files etc.

Steps to reproduce:

$ display -window root /path/file.jpe &
$ top

Uses much CPU here but doesn't leak mem. Try to rebuild it with debugging symbols. Here is such a version. http://pkgbuild.com/~jelle/imagemagick-6.8.3.10-1-x86_64.pkg.tar.xz

Autorun: display -geometry 1920x1080+0+0 -window root /home/alex/.fluxbox/wallpaper-514880___2.jpg

"display" freezes

process "X"consumes memory
