Let me take a wild guess - you're running in 16bpp?

There are very few pure-greys in 16bpp mode because the green channel
has an extra bit, and the normalised 0->255 mappings for the colour
channels don't sync very often (do the math if you are dubious ;)).

Of course, this may not be the problem.  But I suspect that it is. :)
There's nothing better than GTK can do here.
