Distorted images in LR Develop mode

[jorgevelafoto]

This is the first time I syncronize my photos from one computer to another. In this case, I syncronized my photos from a Windows computer to a Macbook Pro (mid 2012). This only happens in some pictures, the rest are okay.

OS is up to date, I tried to uncheck GPU processing in LR preferences but still doesnt work. Any idea?

Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Past that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut as that is just so much dead space to us non-Techs.

How did you 'synchronize' one computer to another? Detail the exact steps you used.

I do notice you only have a 'Smart Preview" available (see under the histogram).

Where are the original files?

Can you re-link the original files and re-build new Smart Previews?

[jorgevelafoto]

Thanks for your reply. The complete process until I got this issue is the following one:

First of all, import all the RAW files to Lightroom Classic. Then I always choose the option "Copy", so the RAW files are copied from the SD to my computer. When import is finished, I select the collection and check "Synchronize" option. Then it sync the pictures and when sync is finished I go to my Mac computer. A pop-up appears now that asks me to syncronize this computer, and I say yes. Pictures get syncronized. I think that's all the process I follow.

It's remarkable to say that this issue only happens with vertical -portrait- RAW files, while it doesnt happens with landscape files.

Sorry for my English, I hope you can understand me well.

I see that you are editing / have an issue with a Nikon raw file.

Has this been edited in any other software?

[jorgevelafoto]

No, these are RAW files that come directly from syncrhronization in Lightroom Classic, from another computer.

They have not been edited in any software previosly.

Thanks for your help.

Quotes in red-

First of all, import all the RAW files to Lightroom Classic.

Your original camera files are never IN Lightroom. They do not import "to Lightroom Classic" They import to the folder Destination in the Import dialog on the Windows computer.

Then I always choose the option "Copy", so the RAW files are copied from the SD to my computer.

Correct in the Import dialog. They 'Copy' to the specified Destination folder. (Not a Copy using the OS)

When import is finished, I select the collection and check "Synchronize" option.

This function (the Cloud icon and Collection sync) is for sending Smart Previews to the Cloud where you can view and edit with 'MOBILE' versions of Lightroom- not another Classic installation.

Then it sync the pictures and when sync is finished I go to my Mac computer. A pop-up appears now that asks me to syncronize this computer, and I say yes.

Pictures get syncronized. I think that's all the process I follow.

Wrong to try and 'Sync' another Lr-Classic Catalog on another computer! (Mac)

You can only ever sync ONE Lr-Classic Catalog to the Cloud. If you swap the Sync to another computer it now takes over all sync processes, and downloads all Cloud files to the Macbook Catalog (different to the Windows catalog!). And you do not have full-size files in the Cloud to download to the Macbook as it would only have Smart Previews!

It is still possible that the Graphics driver is causing the image 'stretching', BUT your attempts to have the same catalog synced on two computers is not possible by your methods!
