Memory Leaks (Or what appear to be)

Lightroom Classic v13.0.1

Appears to suffer from huge memory leaks which after a few minutes use bog the my machine down so much that I have to wait seconds at a time for the mouse to respond!

Below is the system info as reported by Lightroom Classic just after opening and then again a few minutes later after editing some average sized photographs. (Taken as RAW on a Canon EOS 5D MKIV)

You'll see the difference in memory usage. It's just a joke!!

The only cure I've found is to close Lightroom, wait for my machine to clear itself up and then open it again. Hardly practical when you have 300 odd photos to edit and you're having to close the application every 3 or 4 pictures...

I chatted to some disinterested 'technical support' person who's only suggestion was to uninstall and re-install Lightroom. I didn't have time then, but have done this since and guess what - it made no difference whatsoever.

I have a pretty powerful machine, 20 cores, 32GB RAM, acres of disk space and the app and catalog live on SSD.

Has aonyone else come across this issue with the most recent versions of Lightroom Classic? It's only started happening in the last couple of releases....

One other thing I notice is that on the odd occasion when I use the AI Demoise feature, sometimes it flies through in a few seconds and does (usually) a pretty good job at cleaning up noise artifacts, but other times it can take several minutes to do the same thing...? Why??? If I look at the GPU usage when the Denoise feature is active, it's maxed out at 100% regardless of whether the image is cleaned up in seconds or minutes.

Any thoughts appreciated!

Your spot on with your assessment and timeline. This memory problem with LR has plagued me also, so much so I've downloaded a competitors software and will move over it it isn't resolved. Its not our problem to solve. This belongs squarely with Adobe.

I'm so close to doing that, but I shouldn't have to for a paid subscription application. It should just be fixed by Adobe but they just don't care in the slightest. From what I can work out the issue isn't affecting everyone that uses Lightroom Classic so they couldn't care less. I'm not sure what is causing the problem other than poorly written software. Maybe if you have a machine with enough grunt to combat it you don't see the problem so much. I think my machine is rather powerful and very highly specified and it has no problem chewing through 4k video editing or anything else I ask of it. Just Lightroom. Even Photoshop works fine apart from the odd bug in it. The longer this goes on the more I hate Adobe with a passion!

Your System Information did not include the Library Path. This can be important IF it includes OneDrive in it.

I trust that yours does not?

Hi - Thanks for your response.

I do not even have Onedrive installed on my PC and I don't use the Adobe cloud storage either. Everything is local. The Library is on SSD.

Hi. You're describing a different issue to the one I'm experiencing. I only have 23k pics in my library (compared to your 190k) and haven't seen any significant issues with searching etc. My issue down to excessive memory usage while editing images in the Develop Module. Lightroom hogs whatever the machine has available and doesn't release it causing the machine to slow down and LR itself to become almost unusable. Closing it and opening it again clears the issue until it happens again which could be the very next image I edit. It's SHOCKINGLY bad!!!

I've been having the exact same issue. Primarily with denoise AI since it released. First few images will fly through the processing, but it progressively gets slower until eventually I quit the program, or it crashes. I then have to wait a few minutes for the memory to clear out.

My CPU is getting on (AMD 1700x), but the GPU is a 3070 and I have plenty of ram!

I've been meaning to try out "Lightroom" (cloud) to see if it suffers from the same issue...but don't want that to be the thing that pushes me into the cloud based workflow.

It's hugely frustrating and I really notice how much time is being wasted on bigger jobs 🫨

So we're now on Lightroom Classic 13.5 and despite me spending £500 to replace the graphics card in my system with something vastly more capable (which has delivered good results) the "memory leak" issue still remains. You can be working on an image and suddenly memory usage on the machine will jump from 4GB to 19GB. When this happens my machine becomes sluggish and Lightroom itself crawls along painfully slowly until you are forced to close it and start it up again. My suspicion, like many others have noted, is that the masking tools are consuming vast amounts of memory and never releasing it.

Adobe you are an utter joke - On what planet do you think it's acceptable to release such poor quality software, charge a subscription for it and never address the feedback from your customers? GET IT FIXED!!!

There have been many reports of this, see the link below. Not sure if Adobe has figured out where the issue is. They may have trouble reproducing it consistently, because for example I haven‘t seen it on my 32GB M1 Pro, Lightroom Classic runs great practically all the time. Yet the reports, about excessive memory use leading to a slowdown, have been rolling in for months, so it doesn’t look like just a few isolated cases:

Thanks for your reply. As someone that has worked in IT all my life and been a developer for some of that time I find it incredulous that an organisation the size of Adobe is happy to charge a subscription fee for software that clearly has issues and does not invest any effort in fixing it. It may be tricky to replicate, but thats why there are test teams and why they should be speaking to customers experiencing the issue and replicating it for themselves. It really is not accetable to publish faulty software and not address any significant bugs identified in a timely manner.

Fully agree. Same issue here, been happening for at least 6 months.

What's more, some moderators in this forum end up closing the threads as time goes on without a solution, many times blaming the OP or other users who experience the same problems.

in the future, to find the best place to post your message, use the list here, https://community.adobe.com/

p.s. i don't think the adobe website, and forums in particular, are easy to navigate, so don't spend a lot of time searching that forum list. do your best and we'll move the post (like this one has already been moved) if it helps you get responses.
