What highlight?

That image got corrected, however there are a number of images that have issues. I've done some digging since then and it seems to be a known issue. It is all related to rsvg. If you use firefox to view the svg they look correct, but on the wikipedia they have issues with z-order. Here are some other examples:

http://commons.wikimedia.org/wiki/Image:Nuvola_apps_package_graphics.svg

I've added descriptions on the discussion pages.

Assigning SVG bugs to Ariel -- need a cleanup pass to see what's fixed up by a librsvg upgrade, what can be resolved with fixes to our font configuration, what can be fixed on our end, and what still needs to be pushed upstream.

giving SVG bugs back to the pool.

Issue still real after the latest svg update on the servers.

I don't see the issue at https://commons.wikimedia.org/wiki/File_talk:Information.svg -- both the 204 and 205px images look the same to me (with highlight).

Can you confirm after forcing reload of the thumbnails?

Only one of the examples above triggers a 'part of the image doesn't show at some resolutions' that I can see:

Original SVG:

At or below 173px wide, the pencil does not have a shadow in rsvg rendering:

At or above 174px wide, the pencil's shadow does display:

The image there are the current versions, not the originals. We seem to have several of these bugs where when a component is rendered 'too small' or 'too large', the component seems to disappear all together.

This bug seems fixed now.

No not fixed:

There is still clearly a difference. Be sure not to use the new version of this example, which isn't affected by the bug.
