P: using arrow keys to navigate through images an image gets merged with the last one

Arrowing through a number of images suddenly this image was overlayed with the previous one. Restarting Lightroom Desktop 9.3 on my MacBook Pro M2 Pro did not fix this. I was able to use the Versions tab to revert the image. Then I started arrowing through again and a minute later the same thing happened to a different image. At the time I wasn’t processing anything heavy on my MacBook, but the fan was running pretty fast so something was going on. A few minutes later and I now can’t duplicate the issue.

Try #3, since apparently these forums aren’t great at saving information…

Description of Issue - Superimposed image appears in Develop module

Lightroom Desktop Version Number - 15.4.1 [ 202606201310-b9f148a4 ]

OS Version Number 26.5.2, M1 Max 32GB 10-Core (has been present in prior OSesm though)

Camera Model (sometimes necessary) - Fuji XH2

Step-by-step Reproduction Instructions (in precise terms, please)

Open catalog, make adjustments (Basic, Detail, Calibration, Lens Correction)
Sync to a various number of photos (varies each time)
Arrow left or right and the superimpose image will consistently appear

Quitting LR removes the issue temporarily, but it reappears 1-2 images after restarting

Clearing photo and video cache doesn’t seem to have an affect

Switching GPU mode to Custom and GPU Preview to off seems to resolve the issue

Switching back to GPU mode Auto fixes the issue temporarily but it will return

Uninstalling and reinstalling LR didn’t fix the issue

The Expected Result

A single, clean color image

The Actual Result

The colored portion is the image that’s superimposed. The black and white portions (which are actually supposed to be color) are the currently selected image)

Any ideas for fixing this?

Greetings all,

A new update for the Adobe Photography products has been released. The June release contains an update regarding this issue.

If you do not see the update in your Creative Cloud Application, you can refresh it by pressing [Ctrl/Cmd]+[Alt/Opt]+[ R ].

Note: It may take up to 24 hours for your update to be available in your Creative Cloud app.

Thank you for being so patient.

Note: The fix only affects items going forward. If you have any older images with this issue, they will need to be restored via the Versions mechanism.

I feel like this is one of those issues that would've been encountered much more easily and caught by Adobe before release if more regular testing were being done in suboptimal environments (such as when dealing with albums full of high resoluton photos or using systems with lower specs, as this was quite clearly an issue with the timing of different components getting out of sync (in this case, some auto-saving/applying changes component was clearly not aware of the user changing files, which would only manifest as an issue if the auto-saving were delayed enough for that to matter).

This isn't the first time I've encountered a bug that I feel is easily observable when using a less responsive system where the timing of components can become out of sync (either due to lower hardware specs or more demanding files), and that's why I continue to ask the questions I've asked in the past. For instance, the histogram delay issue I reported still goes unresolved, and that rather obviously seems to me like another case of a performance-related issue involving out-of-sync components.

How does an issue like this get past a multi-billion dollar corporation's QA?

“How does an issue like this get past a multi-billion dollar corporation's QA?”

Easy. The customers are the QA team.

Not only do we test the product for free, we actually pay increasingly expensive subscription fees for the privilege. We find the bugs, collect the evidence, prove the issue exists, and perform the mandatory troubleshooting dance: clear caches, rebuild indexes, reinstall everything, reboot twice, and pray.

It's a fascinating business model when you think about it. OSS projects do this because they have to. Multi-billion-dollar vendors do it because apparently they can :)

Hi, I seem to be having the same issue: Images become randomly rotated, particularly when adjacent to other rotated images. Also, when moving quickly from image to image, the edits from one image (e.g. saturation, exposure, etc) are sometimes applied to the next image (adjacent) being worked on.

This happens predictably and repeatedly on a MacBook Pro. Seems like a bug. Would appreciate a fix.

When I select the selected photos the edit from one automatically transfer to the image next to it and I lose all my work. I just lost 45 minutes of editing on two photos. Just horrific!!! The same thing happened last night and I had to continue to redo edits. This is unacceptabe!

Hi @mtassi33, that sounds like a separate issue than this one. Are you experiencing issues when toggling between images? If you’re experiencing the same behavior, hang tight! We are working a fix for this soon.

If that’s NOT the case, I would recommend creating a new post with the following:

System Info: Your system info can be obtained by going to Help > System Info, copying and pasting it into a text file, and attaching it here.
A numbered list of the exact steps needed to replicate the issue.
Expected result - what should happen after executing the last step.
Actual result - what actually occurred after the previous step.
If possible, a screen recording or screenshots of your work area.

Once we get that information, we can help you troubleshoot the issue. Thanks! ^CH

Yes it is when going back and forth between images. It’s really bad. In fact it is maddening. I thought of going back to a prior version because it is really impossible to deal with.

Lightroom version full of bugs! Copying settings across photos, rotating photos, overlaying two photos all randomly occurring without prompting. It’s coping masks, remove edits and things without reason. Spend time editing a photo and it undoes all the work. Unchecking denoise and rechecking resolves the double exposure effect, but these seem related to carrying settings across from different photos in the gallery.

Lightroom will randomly force a double exposure between images when editing without a way to reverse it, this impacts both the preview and exported versions of the image. It is a severe bug impacting my work & I may miss a deadline because of this bug. Restarting Lightroom CC didn’t fix the issue and the image looks the same when viewing the cloud sync version through Lightroom on my phone.

This is with Lightroom CC version 9.3.2 build 20260526-1830-0f9d875

Good news! I found a potential fix if anyone else is having this issue in Lightroom CC. It has something to do with the “Denoise” tool in the Details tab. Unchecking Denoise, updating selection settings, and re-applying denoise removes the double exposure problem.

EDIT: While this removes the double exposure bug, it deletes all of your masks on the image losing progress. Adobe PLEASE fix this bug ASAP..

Still seeing this bug after having switched to macOS Tahoe from Windows. Also sometimes instead of merging, the photo you were on completely replaces the previous or next photo (encountered by using arrow keys to adjust the tone curve, and accidentally holding left or right, which quickly scrolled through multiple images, and completely replaced the first image it switched to with the original image I was adjusting the tone curve on).

So far it seems that turning off “Loupe Info” helps with the issue (Cmd-I) - I will post an update in the next few weeks if this is the solution/workaround for LrC bug.
