The rendering of a photo in develop is sometimes less saturated than it is in library.
To reproduce:
Select a CR2 file in library with loupe view on a second monitor. Switch to develop, the saturation decreases slightly. Switch to library and the saturation increases slightly. Switch back to develop and the saturation remains the same Move the contrast to 10 and then back to 0 and the saturation decreases.
I expect that "Solved" means that the solution is the internal fix that will be distributed with the next release (either RC3) or final 4.1 - it's only my own interpretation.
This is unsatisfactory Adobe. I am not a happy camper. I use 2 displays for my workflow. FIX THIS and GET IT TO US ASAP. Fix the gallery export, slow response of sliders, slow performance in general, etc. You are costing me a lot of time and money. Get it together, please.
