Bizarre inconsistency, possibly buffer overflow

[ianr]

It appears that gradients drawn, here between pure black (#000000) and pure white (#FFFFFF) have very odd fluctuations in areas that are supposed to be purely that color, specifically, one off on one digit for each. This seems to be the case regardless of which colors are selected.

 

The pockets outside the magic-wand selection at 0% tolerance vary, on black between #000001, #000010, #000100, #001000, #010000, and #100000, and on black between #FFFFFE, #FFFFEF, #FFFEFF, #FFEFFF, #FEFFFF, and #EFFFFF. It seems to me to be a possible buffer overflow bug.

This is an option of drawing a gradient.

If you don't want it, disable anti-aliasing when drawing a gradient:

So, you can see, this is not a bug. The software is working as designed.
