Lightroom Classic: (Mac) User Interface slow after upgrading

Hello,

Since upgrading to Lightroom Classic v10.0, all UI-related functionality is painfully slow. All editing functions are working correctly and quickly but scrolling through the catalogue or even scrolling a side panel is taking many long seconds to refresh. Unreasonably long.

Disabling GPU Accellaration has no affect on my Lightroom's performance.

macOS Mojave 10.14.6

Mac Pro (Late 2013)

3 GHz 8-Core Intel Xeon E5

32 GB 1866 MHz DDR3

AMD FirePro D700 6 GB

Greetings All,

Thank you for continuing to provide information and for you continued patience.  This thread is tracking Mac issues related to a small group of customers who  are seeing issues with UI speed in Lightroom Classic 10. If you are Windows user or not using Lightroom Classic 10 you should create a fresh thread for further diagnosis. 

Update 11/23/2020: The team is continuing to actively work with third parties to determine the root cause and solution to this poor experience.  Stay subscribed to this thread as it will be your best conduit for information regarding this issue. 


For review: 

To diagnose: 
Substitute Adobe RGB or sRGB for your OS Monitor Profile in place of any custom profile you've created using a colorimeter tool or your monitor's software. If the system returns to normal speed it is due to this issue. 

Available Temporary Workaround to try: 
Revert to version 9.4 of Lightroom Classic via your Creative Cloud App. 9.4 does not have this issue and reverting should restore you to the behavior to which you were accustomed. 

Members of the engineering team may be contacting you for additional information and perhaps copies of custom display profiles. Thank you for any help you can provide to them.

This post will be updated as soon as more information becomes available.

Sorry for the misunderstanding. The profiles from colornavigator cause this problem. my post was an answer to the post above:
"Members of the engineering team may be contacting you for additional information and perhaps copies of custom display profiles."

Sorry that was my fault for not looking first at what you were replying about. So far I am thinking that enabling the GPU causes something with these custom profiles. It would be nice if more people tested this slow down with GPU disabled and then enabled to see what difference can be found. Maybe a memory issue with custom profiles and GPU enabled.

@Rikk Hi Rick, we are having the same problem as everyone else but I didn’t want to add our details as we are using a 2019 Mac but with only 8GB RAM and I knew everyone would say it wasn’t enough.  However, before the update it was working perfectly.  The point is, I did as you suggested and reverted back to v.9.4 but somehow I have lost all the images!!  What did I do wrong??  Any ideas would be greatly appreciated.  Thank you.

It sounds like you opened the incorrect catalog.  You need to search your computer for files ending in .LRCAT and review the recent files until you find your working catalog.

Hello Rikk, I have the same super slowness issue with an MacPro 2019 + Radeon Pro 580X_8GB and the Apple XDR 6k Display. If I use my DELL Monitor 34-Zoll (3440 x 1440) it's incredible fast. 
Then I tried resXtreme to lower the resolution on the XDR-Display just to FullHD, there is no change in performance. 
Only when I switch to the Apple color profile "Internet & Web (sRGB) and the full 6k resolution, the performance "normal-slow" is back (like before the LR10 update).
Please resolve this issue soon. If needed you can contact me.
Thank you in advance.

Regards
Ronald

Switched the color profile to Adobe RGB on both my NEC monitors from icc profiles calibrated with Spectraview II (sRGB? Not even going there).

At least the scrolling performance in Library module has improved, but the same amount of lag when selecting particular image(s). 

Mine is a dual monitor setup, the main is a 4K monitor - NEC PA322UHD - where the main window resides. The second monitor - NECLCD2690WUXi2 - displays secondary display, grid view 99% of the time in both library and develop modules.

Develop module has been relatively unaffected. Dual screen display enables me to keep the grid view open and perform some Library functions that way but switching from one image to another is frustratingly laggy.

In my time owning 2009 Mac Pro that has been upgraded incrementally up to almost its maximum performance capability over the years to keep up with software requirements (and it is still well above the LR hardware requirements), I have never seen so many spinning beachballs - not just in LR but in any software and their applications.

If you unhook the 4K and do nothing more, any difference?

Yes, like night and day. I did not bother to physically disconnect but just turned off the 4K monitor and restarted Lightroom (not even a reboot).

Unfortunately, the other monitor is rotated 90 degrees to portrait orientation due to space constraints and basically unworkable without modifying the entire panel. While workspace is still roughly equivalent to that on a 15" laptop screen, the resolution is much lower and I'm working from 1 meter away.  Not a practical solution.

On the other hand, we were able to isolate at least one factor that is hindering the performance - thanks for the suggestion.

Well that's now to be expected (4K being part of the issue). Good to know. Adobe's on top of this, I suspect they have enough info to get it resolved but what we (and of course they) know is that the profile and type of display are part of the cause. 

I wonder if when drives a 4K display at less that this resolution, that clears up the problem?

I just tried that, too (turning off one of my 2560x1600 displays). It doesn't make a difference at all in my case. Interesting, isn't it?

What does make a difference in grid view usability on my setup is minimizing the thumbnail size and turning off extras and badges (View > Grid View Style...). Still far from ideal, but definitely better...

I opened lightroom today after deleting a number of files last night and bang zipped along, for about 3 photos and then steady degradation affecting the whole computer. Photoshop won't even open. Stuff popping up making me go what??? It's as if all the commands are spaghetti. Finally computer froze and had to shut off and turn back on. Not Acceptable. Imac running Catalina, 16 GB ram.

Tip, on Windows, Lightroom gives the best performance in single screen mode with the Lightroom window at full screen. 

 

Sad to say but you folks are using old and slow video cards with old and slow processors. Also as ATI is primarily focused on the gaming market, $for$, their cards tend to be slow for photo or video editing. 

 

Yes, Nvidia needs some competition in this area but since the effective demise of Matrox; they are the only game in town. Maybe we could crowd fund a video card focused on photo editing, just joking of course as we'd still have to use a Nvidia chip. 

 

Recommendation for 4K monitors, consider a 8GB Nvidia Quadro if there are drivers for macOS. For 5K monitors, 11GB would be better. 

 

Lastly, each new release of Lightroom provides several performance improvements and usually at least one slowdown. For V10, we took at hit with scrolling in, mostly, the Develop module. But the balance overall is a significant improvement. On my machine (6-core Xeon, Nvidia Quadro, dual 4K monitors), the hit is very minor.

Here is my card - The Radeon Pro Vega 56 is a professional mobile graphics chip by AMD, launched in August 2017. ... AMD has paired 8 GB HBM2 memory with the Radeon Pro Vega 56, which are connected using a 2048-bit memory interface.

The Vega 56 is on Apple's maybe list. "Metal" support is required for Lightroom to make use of the card. 

 

The following cards are known to be Metal-compatible: 


MSI Gaming Radeon RX 560 128-bit 4GB GDRR5
SAPPHIRE Radeon PULSE RX 580 8GB GDDR5
SAPPHIRE Radeon HD 7950 Mac Edition
NVIDIA Quadro K5000 for Mac
NVIDIA GeForce GTX 680 Mac Edition

 
Apple also lists cards that "might also be compatible" with macOS Mojave: 


AMD Radeon RX 560
AMD Radeon RX 570
AMD Radeon RX 580
AMD Radeon Pro WX 7100
AMD Radeon RX Vega 56
AMD Radeon RX Vega 64
AMD Radeon Pro WX 9100
AMD Radeon Frontier Edition

@bill_3305731 6GB of VRAM isn't enough to scroll some content in a window? Come on… Especially since it worked nicely in the previous version and every other application - including other Adobe ones.

I appears that your video card is unsupported. Technological progress I guess. 

 

On Windows with both 4GB and now 5GB Nvidia Quadro video cards (4K monitor), scrolling was fine but has slowed down with V10 but only a little; just enough to notice.

In the Performance tab in Lightroom's settings, it says the the GPU is fully supported. Plus, all the actual heavy lifting editing functions work quickly as expected. And actually, now that the adjustment brush is GPU accelerated, that works like a dream as well.

It really just the UI that took a hit this update. At least on a Mac, I can see something definitely changed in the way the UI is rendered but I can't put my finger on it. The font in the Develop module's drop down lists is different. Something was definitely updated but there's clearly a bug here.

This is a good example of when Adobe would really appreciate a video recording of what you're seeing. Regarding the font, it seems like it was intentionally changed throughout the interface. Win 10 here.

Hi, i figured out, that with calibrated monitors on MacOS the library view in Lightroom CC v10 is round a bout 20 times slower, than with monitor profile "apple RGB" chosen. The editing section is fine and run flawlessly  with the profiles from calibrated monitors.

Here we have EIZO monitors with color navigator software on catalina. We  can reproduce this behaviour through all Macs in our whole company.

The same behaviour is in Indesign v16 and illustrator v25.  Adobe Photoshop does not have this issue... !

It does not matter if I build the profile with EIZO Color Navigator or with i1Profiler from XRite (always ICC version v2).

 

It is awful. we cannot use the Adobe CC anymore.

I have yet to see this problem with ID16 but here again I do not have GPU Performance selected. Will try to select it and see what happens.

Upon upgrading from v9.4 to v10, certain UI actions in Lightroom have become incredibly slow.  The most noticeable is scrolling in Library Grid view.  I experienced no lag/hesitation in any of the 9.x versions, but in version 10, scrolling in Library Grid view is almost unusable (several seconds to scroll a couple of rows).  I downgraded back to v9.4 and all lag went away.  I'm running a 2016 Macbook Pro 16GB RAM with Radeon Pro 455 2GB VRAM. MacOS Catalina 10.15.7.

Glad to read this as I noticed this slowdown on my iMac too. (I reverted to 9.2.1 though, due to the clone/heal bugs when used at the frame edges, which were introduced in 9.3).

Thanks for brining to my attention the fact that you can actually downgrade.  I have gone ahead and downgraded both Lightroom and Photoshop, in which they've removed the line-arrow pixel tool for no good reason.  I've also disabled automatic updates for Lightroom.  A complete disaster.  Adobe takes our subscription money and then releases half-baked software to us like gunea pigs.

Still requires a video card supported by Lightroom. Unfortunately Adobe has stopped listing supported video cards so for other than mid to high end Nvidia cards, it's a guessing game. The Vega 56 is a "maybe" card.

 

Business reality: if 1 in 10 thousand people with a computer do photo editing and maybe 1 in a thousand of them do it on a Mac with an AMD video card... You get the picture. 

 

Based on your experience, a change in Lightroom v10 probably pushed your card from the "maybe" category into the "unsupported" group. Adobe delivered a significant number of significant performance improvements with V10. It is likely that those improvements will be a setback for some hardware. AMD and Nvidia use significantly different APIs for communication with the card. Add in the variations from one card architecture to another within a brand and the problem becomes obvious.

Yet here we are after spending $6000+ on computers less than 3 years old, our work is coming to a stand still. Even though Apple says they are supported and Adobe says GPU with Metal Support work. And even if they don't support, why is it slower than it was in 9.4?

Same here. 16" Macbook Pro, 6core, 32GB ram, 5500M 8GB, and after update to LRC V10 it is unusable! With last version it was ok, not blazing fast but 100% usable for work. Now it is working approx 5 times slower. Changing modules, copy and paste photo settings. I am also working on desktop with Ryzen 3900X, 64GB ram, RTX2070Super and after update the performance is same or maybe even little bit faster. So I updated also on my MBP and its disaster :(

$ for $ laptops are much slower than desktops. Nvidia cards are faster than AMD. As hardware gets pushed by software for better performance, the fast equipment gets faster and the slow equipment... Well you get the picture. 

 

Your MBP is great for Linux software development but for high performance photo or video editing, get a $4-6,000 gaming laptop to compete with a $2-3,000 desktop.

I know $$$ laptops has similar performance like $ desktop. But this is a 4000$ notebook that could handle the software very nice till today when I updated it. If I was using some crap 500$ notebook I will understand it but this is a "pro" machine and if it cant handle 24mpx raw files there is some problem. And in my experience, the problem is in the software. Or we are now in a time where high-end machines are usable only for one year and then they are good only for youtube?! I also work in Premiere Pro and Davinci Resolve and I learn something there. When you have two software that can do the same thing and one can do it a lot faster than the other on the same machine you can tell that the problem isn't in hardware but in software optimization. I am downgrading LRC and wait for Adobe to FIX this.

Bill you say Adobe doesn't list compatible cards.  If I was to add an external GPU to my iMac Pro how would I find out which model would be compatible with Lightroom?

598 Messages

 • 

7.5K Points

Recent Nvidia Quadro and GeForce cards should be fine but there is always the issue with MacPro compatible drivers.

 

In your situation, I would contact Nvidia support though they are likely to recommend the latest cards. And check with Adobe support to see what they say about the problems you are having with your card. They might already be planning a fix. That would be free. 

 

Also measurements I've taken, reported in another thread, indicate that Lightroom is making much heavier use of the processor to provide performance improvements. All develop tools that I've tested are now instantaneous on my Windows Xeon 3.6/4.0 GHz machine with most of the improvements coming from heavier use of the processor. 

 

People who don't know how video cards work think that we would unconditionally benefit from Lightroom increasing its use of the video card. However for many functions, a video card is a bottle neck. This is especially true if the whole image won't fit on the card. Just take one unrealistic example, if Nvidia were to release a 32GB version of the P4000 and Lightroom were to require that card; we would see a speedup for most functions. But not all. 

 

Of course, the most straightforward solution for you is to switch to Windows, notice the flood of problems primarily by Mac users. Think what it is going to be like with a new version of Lightroom running on the totally new version of MacOS on a new hardware architecture. This forum is going to be buried with bug reports.

I didn't read your question correctly, my mistake. I don't believe that Lightroom will work with an external GPU. Saw that posted somewhere but don't remember where it was.

Can you just stop? I've read this whole thread and you've repeatedly spouted nonsense. You obviously don't know what you're talking about, but feel compelled to advise anyway.  

Please, please stick to topics that you know something about, its not helping anyone.

I'm in the same boat.
Mac Pro 2010, 2x3.46GHz, 28GB RAM, 1TB Evo SSD, Radeon RX580 8GB

I've done all the usual checks and tweaks like turn off sync, address, face, turn off/on GPU acceleration, purge cache, build 1:1 previews, delete previews, then rebuild them again.
The only thing that speeds it up is if I resize the Lightroom window to less than half of my screen (4K 27") which is not ideal.

I have exactly the same configuration and exactly the same problems.  Tried all the usual tricks.   Applying presets in bulk, which took 10-20secs in 9.4 now takes 10-20 _minutes_, and then Lr insists on rewriting all XMP data.  Also, Delete Key no longer removes a gradient, and when removing using menu, the animation is gone.  Seems to be some other weird UI things happening, its quite disconcerting.

I can't recall ever having performance issues with Lr before....

@davidmantripp  :-  Can you please provide more details on the slowness issues that you are facing? 

We have tried to compare apply develop presets to 1000+ images to compare the time between 9.3 and 10.0 but it almost took the same time.

Can you share the develop preset that you are applying on the images and if possible, a recorded video would be of great help.

Please share the dropbox/we transfer link and send it to mayugupt@adobe.com

Thanks for reporting.

It is a problem with the profiles, not with the hardware. The image rendering in Lightroom (Library module), Indesign and illustrator also is broken. Here you have a youtube vid, which shows the mess. It is in german, but you can see exactly what i am doing and when the image rendering in lightrooms library module slows down:

Is anyone having these problems on a Windows machine? If this is strictly macOS, that will help the Lightroom developers isolate the issue.

I am not. Like I said above my desktop rig with 3900X, 64GB ram, RTX2070Super with latest Win 10 works great. Dont know if its due Nvidia GPU in the PC or slower HW in MBP.

After years of complaining about how slow LR Classic is, the latest 2021 update brought me great joy... at least for the first two sessions I was using it. It was flat out peppy! Images were opening fast, going through the pick process was moving at a rapid clip. 

 

Then today, the third session I'm using LR Classic 2021, it's BOGGED down slow. Slower than 2020 previously. I restarted the computer, left all other apps closed, and same speed behaviors. 

 

I am running the latest MacOS Catalina 10.15.7 and have made no OS or software updates after updating LR Classic to 2021 version. 

I'm running on a 2019 MacBook Pro laptop with no other issues of any kind.

I'm getting the same problem, latest OS but on a 2013 iMac (yes, I know its old but was working with Lightroom very well prior to the update.).

What was a simple task previously such as spotting out dust now beachballs for 2 or 3 minutes.

I would love to be able to recommend updating but Lightroom doesn't seem to be quite ready yet...

Can you change monitor custom profile  to "SRGB"  and share your feedback ?

 

Thanks

I'm running on macos 10.14.6 on a Mac Pro 5,1 with maxed out specs and a Radeon VII graphics card. My Lightroom library is quit large but this was no problem before. I switched back to version 9.x so I can use Lightroom again. Version 10 was not usable at all, freezing all over the place.

Note: This comment was created from a merged conversation originally titled After update to version 10 Lightroom is very slow and freezing

Same issue here, hardware seems not the be the reason for the problem:

14-Core i9 10940x

128GB DDR4 RAM

AMD Radeon VII 16GB

Running 10.15 Catalina

New v10 Lightroom is very slow. Seconds after first start it was very fast, soon after everything started to slow. Even the curser lags. Activity monitor on MacOS shows huge CPU usage of LR even when idle.
