1. Open URL.
2. Analyze the pixels around each letter.
3. Especially around "build", the greenish color is out of place.

Removing the filter applied to the text also removes the artifacts.
Those appear even for a filter that does nothing, eg,
<feMerge>
  <feMergeNode in="SourceGraphic"/>
</feMerge>

This might be caused by antialiasing being corrupted or applied too soon, although that's a mere gut feeling.
