Erroneous outlines in PNG renderings of SVG images
Closed, InvalidPublic

Description

I notice something weird going on with this file. If you look at the PNG rendering, it looks like it has a green or black outline around the person, which is not there in the actual SVG file. It is even more noticeable at smaller sizes. I have noticed this before with another file as well, but can't remember which one.

I just came across another example of this: The Wikinews logo. Here as well it is more noticeable in small sizes, see e.g. where the logo is used on this page. It seems like there is a sort of green glow around the sides that shouldn't be there.

Hmm, I just checked in Firefox and the problem is not there. That led me to believe it was a browser issue, and it turned out it had something to do with GPU rasterization in Chrome. Enabling that solved the issue. So it is apparently not a Wikimedia problem after all.
