I haven’t had much time to work with the latest build, but I think I found something that doesn’t seem right. When I reduce the Look offset or the black relative exposure I get purple fringing in pure red regions:
The left is the unedited shot and the right is with the latest AgX module activated (black relative exposure is at -3.65). With AgX off, the inner petal is 165, 0, 2 in RGB. If I darken with offset or Black rel exp then the blue suddenly jumps at the affected zone becomes 154, 1, 154.
Its worth noting that Red matches Blue when this happens.
This occured in Build 766, but only in the blacks:
I only noticed it now because of what I just saw.
Adjusting the new red attenuation and red rotation controls will control the effect, but the blooms become too unsaturated and restoring them under the Look tab restores the problem.
Oddly, neither the red nor the purple indicated out of gamut.
