After a long time without upgrading my system, I have gone from DT 1.4.2 to DT 1.6.6. I have noticed a problem with the Tone Curve Tool, that create very bad purple color zone even when set completly flat.
You can see an example image here : http://chris.stingray.free.fr/tmp/dt_purple.png The raw is from a Sony Nex 6. I have tried the unstable ppa (I am using Ubuntu) and the problem is the same. Since the Tone curve is quite a basic tool, I am very surprised to see this "bug". Regards, Chris
