Easier just to browse to:

And view it at different zooms. The background will change.

Similar corruption is visible in the favicon for https://phabricator.services.mozilla.com/ (shown e.g. in the tab strip). It's got unexpected green corners that should be transparent.

I see the same issue if I view the icon directly and zoom out with full page zoom.

I presume the GMail logo background is the same issue.
