Edit: In considering your post again it looks more like there is an issue with your source image.
Not sure so need more information.
(previous response)
That is often a hint of incorrect setting with premultiplied or straight Alpha channels.
Check that in the settings of your input/source.
In my experience... and going from memory so I might have this reversed:
A white halo often suggests the image is not premulitplied but the application isn't accounting for that.
A black halo is where the image is premultiplied but the application isn't accounting for that.
At the root of this seems to be an earlier decision to accept the lesser of two evils and display the black halo rather than the white because it was less likely to be perceived or to distract.
Give this excellent video a look:

If that doesn't address your issue... What image format are you using?
