I've had problems like that before.  In my understandment, error_bound in the
second pass has to be close to the original, just slightly higher.  It gives
differences in the performance, I don't know, perhaps the data lookup method
depend on the values being close.  The values can't really be the same because
it causes some black splotches, in my experience.

I generally put error_bound in the second pass to be at most 2x the original.
