Unfortunately Adobe has a history of not fixing things they break with a new release until the next release. It has been pretty rare for them to just simply fix one issue and then patch. Twice they have broken the ability to do pano merges in PS, and both times the "fix" was something that happened in the normal course of releasing a new version several months later. The issue with using droplets wasn't addressed until the next release. Of course the famous import interface issue wasn't addressed very quickly either.
Hopefully they would consider this a serious enough problem, but since the issue manifests itself in such a subtle way I'm not sure enough users will complain. This issue to me is serious enough they should push a fix out ASAP, but guessing we'll have to stay with 2015.5.1 for a couple of months.
Hope I'm wrong. 2015.6 seemed more responsive with many functions for me.
Hi Wayne, the presentation of the issue is not at all subtle when one goes about the technical diagnosis with some simple procedures and arithmetic. It is quite stark seen through the numbers, though admittedly can be somewhat less so on paper, depending on the photo. Most of the complaints came from people who immediately noticed a visible deterioration of print quality. Users are complaining. I agree with you that it is a pretty fundamental problem, and as such there should be no hesitation to issue a fix as soon as they actually fix it. One of the whole purposes of the CC approach was to give them flexibility to issue updates, rather than being glued to a fixed timetable. That was part of the ""CC promise" if I can put it that way. So now is the time for them to respect their own previous commitments. Part of the delay we're seeing is the initial period of denial; I don't know how long that lasted, or even whether it is over; but by now they should know they own this issue and need to fix it. When that realization dawns, time will be needed to analyze where the code went wrong, repair it, and THIS TIME quality-assure it every which way, then prepare the release. I don't know how much time all that will require.
Adobe, of course, are being completely unhelpful by not having uttered a word about it since their initial rubbish blaming Epson drivers. Some people are simply irate, while others have been pressing hard on this matter, because of its importance; but you may well be right that perhaps a larger groundswell of dissatisfaction will be necessary to shake them into more responsiveness. We seem to be suffering from a corporate ethos where pride of workmanship takes a back seat to the bottom line and reputational risk means little. Somehow or other that needs to change, and the only effective vehicle I know of is real competition. Where is it, all factors considered?
