P: Sync from previous photo crops the image

I still haven't reproduced using the Sync case but have advised the team that it is being reported as well and likely related. 

If you're in Develop Module, selecting few pictures and clicking "Previous" button will sync settings only for that selected picture. The same way if you click delete - only 1 photo will get deleted comparing to Library module where all selected will be affected.

Thank you

From these instructions I am able to reproduce - sort of. 

In step 5, if I select more than one image only the first image is cropped by one pixel. The others are ok. 

I will log a bug with the team for this. 

@Rikk

I'm processing next batch of photos and the behaviour is still there.

1. import new pictures with changed names

2. generate smart and standard previews

3. go to develop module

4. select one of the previous photos that adjustments are good to be copied from (not cropped)

5. go to any photo from new import

6. click "Previous" button to get all adjustments from the selected photo in no 4

7. height is now reduced by 1px and crop thumbnail icon is displayed despite neither of the pictures have been cropped.

6 alternative. Select both original (step 4) and new picture (step 5) and click "Sync..." button

7. No matter what's selected in the Synchronize Settings window, if Aspect Ratio under Crop is selected, the new picture is cropped by 1px; if everything is selected except the Aspect Ratio then new picture is not cropped.

Hope the above is now clear and straightforward for you Rikk.

I can not duplicate this behavior on macOS 10.15.7 either

I've tried it on Mac (10.15.7) and Windows 10 and both systems behave correctly. 

So the question is, what could be different from my computer or my Lr that would cause this?  And, is anyone else seeing this anomaly?

I tried again using your files and this recipe and I still cannot reproduce this. All files end up 8256x5504. 

New test:

1. First picture measures 5504x8256 pixels
2. Made exposure and vibrance adjustments to first image.
3. Shift clicked last image in sequence.
4. Synced first image settings to all others.
5. Checked all image size measurements.
6. First image 5504x8256.  All synced images measure 5504x8254.
7. Reset all images and then ran this test again.  Same results.  The first image dimensions are unchanged.  All others 2 pixels smaller on the long side.
