P: Desktop Memory leak on M1 Machines

[Minh0D4D]

Hi!

I am a software developer. Recently, my Lightroom CC (version 4.2 - 20210301-0713) is very slow . A close look at activity monitor reveals that the app consumes too many threads and memory (attached photos) which freezes the app.

@Rikk Can you help me forward this to the development team?

Thank you so much!

Me too, Ultra with 128GB (20/48), and LRc will consume up to ~98GB, at which the OS stalls with an 'out of application memory' error. For what it's worth, I did solve this on my machine: de-select 'Use GPU for image processing' in Preferences:Performance. 

Hope this works for you, and I hope even more that Adobe is furiously working to fix the many years-old performance issues that the Studio has revealed to be purely Adobe's fault. 

This immediately solved the memory leak, and actually sped up some components of the UI; I notice no deleterious performance issues after making this change. Oddly...

Somehow that got replied to the wrong person, was intended to be @MrhoniKeith...

I just made those changes. Hope that solves it for now. Thanks.

Hello!

I'm having severe performance problems with Lightroom (Cloud-based, Version 5.3) on my new Mac Studio M1 Max. I've just set up my computer and installed the necessary apps (Lightroom, PS, FCP, MS Office - nothing special...). Upon starting the Lightroom desktop app, I'm experiencing extreme lag. Each click takes up to 4-5 seconds to perform the task. It also seems to slow the whole system down - it takes several seconds to navigate through the menu bar, although Lightroom isn't doing anything (no exporting etc.).

I've tried to reinstall the desktop app, but it's still lagging - to an extent, where the program isn't usable any more. All other apps seem to work fine (Photoshop, FCP, even the web-app of Lightroom works smoothly - as i would expect from the desktop app). I have a Mac Studio with an M1 Max chip and 32GB of RAM - so the hardware shouldn't be the problem. Even when editing with the mobile app on my iPad Pro, there are no problems.

Is anyone else experiencing the same problems - or does anyone have a solution?

I'd be very grateful!

Thanks in advance!

Andy

I've been doing some research, but haven't found a solution yet. Looking at the activity monitor, it seems the memory is ok but the cpu usage is way too high. As you can see on the attached screenshots, LR consumes between 400% (when it's just opened i the background) and 700% (when I'm trying to do some editing) of CPU. Is there any way to fix this?

I'm using a 4k LG Display with HDMI - I use scaling for more space. I found when I'm reducing the size of the window, it seems to use less CPU (around 150%) and therefore running a bit faster - but that can't be the solution, can it? I'd like to use my whole display for photo editing, not just a small corner...

Thanks in advance!

Good morning!

I just have it on my second, brand new MacBook Air. The first one had 16GB of RAM, the current has 8GB of RAM. Start LR, wait 5 seconds: 45GB of System Memory is eaten up. I can not access Prefs or anything in the App.

Thanks

Small Update: Just installed 5.4, and THE PROBLEM IS STILL THERE. Adobe must have recieved hundreds of crash-reports from me alone, I mean: Ist the an Adobe Support existent?

REALLY ANGRY

Thank you for your patience.

Hello, Rick!

If its 5.4 I downloaded minutes ago: No, its still crashing after 15 seconds of doing nothing:

It would be rally nice to use my paid software, I am waiting since month (and two different M1-Computers) to get this fixed!

Angry - very angry: Wolfgang

@wok5 

This thread is not really about crashing but more about memory usage. I think you have a different issue than that being reported. I would recommend starting a new thread with very specific information about systems, workflow, crashes etc. 

I checked out your crash reports and I don't find 'hundreds' For 5.3, I find a total of 4 crashes but they represent three different crash states and in each case, it looks like you are the sole customer in that bucket. If you are experiencing this on more than one machine, I would look for a common software configuration that might be causing the crash. 

The other thing to be aware of is are all the crashes Adobe? Are some of the crashes represented with an OS dialog? 

In any case, I would recommend a new thread as your issue is likely different.

@wok5 

Have you tried switching off the GPU? If no, then please do so and report whether it helps or not.

Are you using an external display? If yes, then please specify the resolution (e.g. 4K) and the scaling setting you've chosen in macOS 'System Preferences > Displays'

[wok5]

I can not access the Prefs. LR just stalls (Beachball of death).

Sorry, to fast: Happens with or without attached monitor...

The crashes are not related to the subject of this thread. Therefore, I think your best bet is as Rikk suggested. Create a new thread and provide as much information about your setup as possible. This would include any other applications or services running at the same time as Lightroom. A screenshot of Activity Monitor  CPU and memory tabs would also be helpful.

Hello, Ian!

I moved to a new thread:
