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.

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.

Please ignore, it doesn’t help :/ yesterday it seems it helped, now I see the behavior very often :(

When going through photos in the details view, when clicking or pressing the arrow to scroll through photos, it will randomly merge a photo with the previous photo without any prompting (beyond clicking through to the next photo).

This started approx a month ago and has been getting progressively worse. The issue is amplified by going through photos quickly so you cannot look through a large gallery of photos at a fast pace or it will start merging far more random photos.

It ends up looking like a terrible double exposure where one of the merged photos goes black and white and the other ends up extremely oversaturated.

It does not rectify itself upon export rather it exports as the incorrect, merged version.

The only way to get the original photo back is via the versions tab and selecting a previous version however it does not recognise the merge as an action as you cannot control or command z to undo it.

I do have photos and screenshots demonstrating the issue however will not attach in this forum for privacy reasons.
I confirm that I am working on the latest version of Lightroom (there are no outstanding updates available) and am working from a MacBook Pro.

Any assistance with rectifying this would be greatly appreciated!

Thanks! :)

Hi @EthanR6iii

Thank you for reporting this. I understand how frustrating it can be when edits carry over unexpectedly to the next photo. To help the team investigate this properly, could you share a few details:

System Info from Lightroom Help Menu (Help> System Info> Copy paste it here)
Whether this happens consistently or only after certain adjustments or tools
Whether this happens only with certain files.

If you have a short screen recording that shows the delay and the edit applying to the next image, that can also be very helpful.

Thanks again for taking the time to flag this. We appreciate the clear explanation you’ve already provided.

Thanks, Srishti Bali | Community & Engagement Strategist, Digital Imaging | Adobe

Lightroom is auto applying (or copy / pasting) edits to my next photo if I switch too fast.

I am running Lightroom v9.3.1 on a MacBook Pro M4. Editing RAW photos from a Canon R6 Mkiii. This is a new bug since the update this week.

When I make any micro adjustment on a photo, and use my arrow key to switch to the next photo, all of the edit settings from the photo I was on get auto applied to that next photo.

Sequence of the bug:

>Editing in Detail

>Finish editing photo A, (adjust exposure by one click of the arrow pad)

>quickly use the arrow key to switch to the next photo: photo B

>all of the edits from photo A are automatically applied to photo B

>if I try to reset the edits (command R) they will not go away. Only leaving photo B and going back to it can I reset the bugged edit.

BONUS:

>tapping back to photo A with arrow pad, that last exposure adjustment I made is not applied.

Further investigation:

In the instance of making a one click exposure adjustment brighter with the arrow pad, I notice that the image reflects that change instantaneously, however I notice the curves take about one second to show that exposure bump… If I wait that one second for the curves to change, then move to the next photo in sequence, there is no auto-apply, and the photo will be untouched, as it should be. I’ve developed a very fast workflow over the years, and waiting one second for a micro-adjustment to apply before going to the next photo will add more time than it sounds. I edit, export, and deliver to clients over 1,000 photos daily.

UPDATE:

I notice if I use my trackpad to slide on exposure it will release the control of the slider dot when I take my finger off the trackpad.. and I am able to switch to the next photo without issue..

Using the arrow keys on the built-in keyboard seems to be where the bug is… I hover my cursor over the slider and just use the arrow keys for my workflow.

The circle on the exposure slider, will stay selected for almost one second after making a change. So even though the photo has shown the edit, it isn't locked in until the slider is deselected. And for some unknown reason, this is causing the edits to apply to the next photo.
