P: Copy/paste setting bug

just checked mine - for me it's same as Auto. Even though it's not exactly same for you, I still believe it has something to do with Auto. What camera brand do you use though? Is it Fuji?

As I said, mine does not behave that way. If I reset, then hit auto, it applies slightly different adjustments. They are all close, within 5 points of each other, but all not quite the same.

Pasted random settings: 


Auto settings applied after reset:

It does turn Auto, with only difference that "Auto" button looks like if it was off, not highlighted. But chose the photo where you have these "random" pasted settings. Then reset all the settings and try to press "Auto" button on it. It will make same "random" settings as you had. 

Ah, got it. 2nd screenshot of the 2nd set of screenshots then :-P. Okay, sounds good. Let me know if you need anything else.

excuse me - make that the fourth screen shot...

I am asking the engineers what information they need for diagnosis before I have you send anything. The Full Report is quite large and I only require that as a last resort.

Not for me. On my computer it does not turn on Auto and all the color and light settings are slightly different each time. And for me, it happens every time on the 2nd copy paste. It is very consistent and repeatable.

Well it has nothing to do with Velvia profile, I never used any of those and still have the same bug. None of the updating or reinstalling helps, though. Basically when you copy settings and Lightroom pastes something what you've called 'random settings' is not actually that random. It copies/pastes same settings except "light" section. There Lightroom applies "Auto" setting for some reason and it's clearly a bug. It happens not all the time, so that something triggers it. Maybe when you touch one setting or another it can trigger this bug. Cause sometimes settings copy just fine. But this bug is really annoying, pissing me off completely already.

Trying to find how to send you a debug / diagnostic report, but I can't remember and can't find the instructions anywhere.

Here's a video of me replicating the issue:

I'm not sure what you mean. The first three screenshots of the adjustments were all using the Velvia profile. In those instances, I first changed the source to Velvia, then copied that over first, without any strange adjustments being pasted. Only when I went back to the original and copied the settings again, then pasted them on the target image a second time did the settings go haywire. On the 4th screenshot of the adjustments above, I tried it without setting the profile to Velvia first, and again, on the second copy/paste, I got the same weird result with the adjustments.

I've been able to replicate the issue more than three times now. I'm not sure what the next test would be. I could replicate this again and then send you diagnostics directly afterward?
