Hmmm... This is interesting. I didn't know that a side effect of the row-hints would be to discard the RGB data from fully transparent pixels. Of course, this makes sense and this is the right thing to do. But this also means that some plug-ins such as Noisify should definitely never use the invisible RGB data in any operation, because the results could be (very) different if some tiles are swapped out.
