Hi,
referring to this post
viewtopic.php?t=24665
I've got the same problem (black halos) with "-selective-blur". "-blur" and "-adaptive-blur" are working fine indeed.

Version: ImageMagick 7.0.1-5 Q16 x64 2016-05-18

Greets,
Christoph

Please show example images and the exact commands you used.

Sorry, just looked like an error but seems to be an unfavorable result of the selective blur algorithm on images with an alpha channel.
Sorry again,
Christoph
