In my series of posts about demosaicing the Fuji X-Pro1's X-Trans sensor, I pointed out considerable chroma smearing in the the raw conversion from a beta version of Adobe Camera Raw. I also clearly pointed out that a beta is, well, a beta, and that hopefully the Camera Raw team would improve the situation in a final release. But I also pointed out that I very much doubted whether Adobe would have allowed DPReview access to a beta that wasn't a good representation of the final product.

Lightroom 4.1 final is now out, with support for the Fuji X-Pro1, so we can expect a final version of ACR with X-Pro1 support very soon as well. (For those that don't know, ACR and Lightroom share a common raw conversion engine, and releases track closely.)

Sadly, the Lightroom final release shows exactly the same chroma smearing as the ACR beta. A crop of the comparable area shown in the original posts is below.

BTW, Lightroom does an excellent job in many other respects - the diagonal edges of the paperclips are just amazingly clean - I very much doubt that any other raw converter could match them. But the chroma is a mess!!

Turns out that X-Trans sensor really wasn't a good idea.
