Blender Version
blender-2.80-513b71c89ad0-win64 April 26

Short description of error
For the Grease Pencil blur effect, it works fine in the viewport.
But for image and animated rendering, if gives off this unwanted edge glow

What I have in this screenshot is a simple black stroke and fill
that's supposed to be like a first person view eye.

if u could look into this. thx in advance :-)

Can you provide a minimal sample file of the issue?

sidenote: I created a minimal copy with the scene that has a problem only
in
blender-2.80.0-git.ee0d8426ab6d-windows64
The issue still does persist in this build.

I also found this to be an issue. I attached a rendered frame. Can provide a minimal sample file if needed as well. Please let me know.

The front parts of the explosion should have a purple glow like the main part of the explosion behind. Instead it has a white edge. If I take the glow off of the back explosion, the white part is purple. After enabling/disabling each object/glow, I think I have concluded that it has to do with the front part of the explosion being a separate grease pencil object in a different part of 3D space. Based off of the poster's image, I think it has to do with transparency and multiple grease pencil objects (in different parts of 3D space). When I disable the back explosion, the glow displays fine.

Let me know if need more info or if anything is unclear.
Thanks
