Hi there,

I’m using 64-bit Arch Linux and yesterday updated my system, thereby also updating imagemagick from 6.8.2.3 to 6.8.3.10. I’m using i3 as a leightweight tiling window manager and have imagemagick’s display utility draw my desktop background that would otherwise just be a boring black area. The command I use to draw the background is executed by i3 on startup and looks as follows:

Code: Select all

display -window root /home/quintus/Bilder/Hintergründe/Hintergrund.jpg

Where the path obviously is the background image to be drawn. I also have a multi-monitor setup, one small monitor and one large, next to each other. As I couldn’t figure out a way to call display multiple times to draw at different areas of the root window (namely on the left monitor and on the right one) I used the GIMP to create one large background image that is exactly the size of the root window, with the invisible part (the two monitors have different resolutions) just painted in pink as I don’t see it anyway. Until yesterday this worked just fine, displaying the left part of the image on the left monitor and the right one on the right. However, since I updated imagemagick, the display command above doesn’t exit at all (but nevertheless properly draws the image onto the root window), but continues to run and run and run, consuming both CPU and RAM, until it finally eats up my entire 8GiB of RAM plus the 4GiB of Swap I have, rendering the system entirely unusable. In order to ensure no other package updates came into effect somehow, I downgraded just the imagemagick package again and restarted i3. It now worked fine again, with display exiting directly after the drawing operation is completed and not consuming enourmous amounts of RAM. I also noted that Conky was heavily flickering while the new display was running.

The last working version of display is this one:

	Before reporting problems, check http://wiki.x.org

If you need more info, please let me know. For now, I’ll pin my imagemagick package to the working old version.

Heya,

I've got the same problem over here, although it still draws the image.

I dug into this a bit and found that revision 10959 broke it severely:
It looks like a cleanup commit, but because the image is not changed at all if the next one is NULL,
the while loop draws the image over and over again.

Would be great to see this fixed soon!

We can reproduce the problem you posted and have a patch in ImageMagick 6.8.4-0 Beta available by sometime tomorrow. Thanks.
