was this in beta 28? I applied a work-around to a crackle issue in beta 29 which
involves reverting to our old crackle cache seed generator. if this is not
behaving as expected, some areas could be mistakenly retrieved from the cache
when they should be re-calculated.

I was just asking if the artifacts are also visible in 28.
I'll check it myself when I get home, can't do it from here.

Save your time, thanks to 29 source available: no artefact in 28.
It's a new 'feature' of 29.
Carlo C posted it in the other branch... too.
