R5 Corrupted Files but Only in Lightroom

[CameraCarl]

I've had my R5 for three years and have an issue that appeared for about 50 images and then went away. There is corruption around the edges of the images where the data is pixellated for about 5-10% of the image area. This is most noticeable on the image of the red leaves. This pixellation appears in these 50 images, then it disappears (as can be seen in the accidental image I took of my foot as I got back into the car after I finished up for the day). The last image of the bookshelves was taken today after I noticed the problem when reviewing my images. I have taken about 300 images since the corrupted images and none show any problems.

The card used was a SanDisk Extreme Pro 128GB CF Express Card. I downloaded the images more than one time and with two different card readers (ProGrade and Lexar) and each time the images are corrupted when using Lightroom Classic (desktop/catalog) v. 13.5. But, strangely enough, I cannot see any corrupted/pixelated images when I view the images on the LCD on the camera, in Mac OS Preview, in DPP or in Photoshop Bridge. I tried deleting the photos from the computer altogether and reimporting them and they still appear pixelated in LrC but none of the other image viewing software.

I'm stumped. Does anyone have a suggestion about why this happens?

It is a bug with the lens profile. Don't ask me what Adobe is doing choosing the wrong AutoScale, because it has been like that for years with RF24-240.

There are three lens profiles for that lens. I think you should go with V2 this time.

Search for AutoScale here at Dpreview.

As you have Adobe Bridge, I assume you have Photoshop, including Adobe Camera Raw. Have you tried opening in ACR? The interface is very similar to LR.

Or turn off lens correction or set it manually in LR. I noticed the one with the problem had a different focal length than the others.

The v3 bug is fixed in the version released today.

Thanks to all. It is indeed the profile. I had read about the profile bug but didn't think it resulted in pixellation. But, sure enough, changing the profile to V2 fixed the problem. I'll reset the profile on all my images.
