Sorry for asking, but i cant see where im going wrong, getting some strange coloration in the composition. ive shown my nodes on the left as im following, and the image previews on the nodes since it just seems to be when i apply the box matte blur. ive kind of worked around it to get an effect i like, as per the image on the right.
just thought id ask in case im doing something daft and cant see it :)
any advice would be greatly appreciated.
Cheers Kent, heres a google drive link for the Blend file, just have to re-add the HDRI image in.

ill download the latest build to check.
might be driver related, or just me missing something simple, does seem to be in the brighter areas in the centre.
Cheers for digging into that Kent and getting back to me, much appreciated. ill have to watch that going forward.
sounds like an overexposure of sorts if they're coupled together when its blending the white part of the mask and oversaturating the input image, another one to add to the toolbelt of gotchas ;)
tried to read the HarkyMan blog, think he put it together back in 2008, but went waaay over my head, heh.
