Unwanted outline when rendering white text on transparent background

Hello,

When I render white text on transparent background there is a unwanted gray outline around letters.

Here's what I get:

I found this topic about the same problem I have: viewtopic.php?t=27108
Answer was that this is happening due to transient bug in ImageMagick, which is fixed in ImageMagick version 6.9.0-7.

I'm using version 6.9.1-2 Q16 x64 on Windows, but I still have the issue.

Any suggestions how to fix it?

Thanks in advance!

I tried installing different versions and here are my findings:

6.9.1-3 - Issue exists
6.9.1-2 - Issue exists
6.9.0-7 - Issue DOES NOT exist

I guess I'll settle with version 6.9.0-7 for now, but I'm still curios why would the issue exist in the newer versions if it was fixed earlier?

Here is the result image I get with version 6.9.0-7:

This seems to be a bug, so I'm moving it to the Bugs forum.

It may be the same bug as viewtopic.php?f=3&t=27683
