Halos with the Gaussian blur plugin
Submitted by Alberto Ferrante
Link to original bug (#779212)
Description
In some cases the Gaussian blur plugin produces some halos that should not be there. Halos are not shown in preview, but they are when the filter is applied (see: https://bugzilla.gnome.org/attachment.cgi?id=343983 ). The problem appears only on masks (both in 8 and 16-bit images).
This problem has been there for awhile, I reported it also in a GEGL bug [https://bugzilla.gnome.org/show_bug.cgi?id=777612], but it is probably a GIMP bug as it occurs only on masks and not on layers.
