P: Slow UI when using Mac and Custom Display Profile

[adamcrowe]

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

I would recommend turning the xmp option on @Aditya Agarwal. Even though I am just a hobbyist, but, also been a dev for over 3 decades and I am sceptical and always keep backups 🙂

It's a minor overhead to start with, but, you are not really concerned if a catalog goes down. You will lose out albums, virtual copies and stacks, the rest will all come back on import.

Thanks... Autowrite XMP slows down Lightroom like molasses when working with complex edits. I usually end up editing like 3-4k images in a day and I tried turning that on, but it just wasnt bearable. 

I did take a backup before upgrading to LR10. But I did so much culling and edits across 5 projects, that it was a sheer pain to downgrade. 

I have been following this thread for a while. While I know, I can figure out workarounds with deep troubleshooting, I simply to not have the time and nor the patience to do so.

No slowdown on my windows machine and considering how little work is involved with updating a XMP, can't see how it could be any different on a Mac.

Since stumbling upon this bug, I've been wondering why using the standard sRGB profile avoids the slow-downs, while the Adobe RGB profile does not. Can anyone in the know share some insights on why this is?

Since the gamut of my displays slightly exceeds that of Adobe RGB, I'd be much happier to use this profile rather than sRGB for the time being...

I have this issue as well.  I'm running Lightroom Classic on a Mac Pro (Late 2013) with 3.5 GHz 6-Core Intel Xeon Ef with 64GB Ram and the AMD FirePro D500 Graphics Card w/3GB Ram.

I'm using a BenQ SW271 Display with a NEC PA272W as a second monitor.

I calibrate my monitors with the Xrite i1 Pro3 Calibrator and use these custom profiles for my monitors.  The colors are right on but it appears that they might be the cause of the problem with Lightroom Classic V10 being unusably slow after the upgrade from 9.4.

Some suggest reverting to the previous version of LR Classic, however, it's my understanding that the catalog created by V10 is not compatible with 9.4, so all of my work (and there's a lot) since upgrading to V10 would be lost, and I'd be forced to use a 9.4 catalog backup that's missing all the new work, so that's not a possibility.

Using a generic profile such as Adobe RGB would defeat the purpose of color management and wouldn't be an acceptable solution.

I'd love to know if there's been any progress defining and solving this issue.  It's extremely aggravating.

+1 for this post *DOUG LANDRETH 

What a nightmare!

[chico11mbit2]

*DOUG LANDRETH  Use the second monitor for the leap with sRGB and the profiled monitor with the custom profile  for editing. Thats just a workaround. But it will work more or less till adobe will fix this.

In my case, the problems with Lightroom v10.x performance on my 2019 5K iMac go away when I set the app to "Open in Low Resolution".

It's ugly (even with the fonts set to "Large" in the LrC preferences, the fonts are very small and a challenge to read in Low Resolution Mode) but it works... uhm... yay? 🙄

Bonus: zooming to 100% is actually useful to properly inspect detail quality that way.

Not all of us have that option. Still not sure what combination of hardware and OS gives you that option. All I know is I do not have that option.

[alexskunz]

@DYP I wrote 2019 iMac 5K but forgot to mention that the OS is Catalina, sorry.

Not all of us have that option. Still not sure what combination of hardware and OS gives you that option

Mac OS for many years has. Click Get Info (Command i) on the application icon. 

[Was DYP]

Not sure why I can't post a screen shot. 

MP2012 10.14.6 No I do not have that option.

[Was DYP]

I guess this was the reason. It must have at least 20 characters.

For sure it is faster. Lightroom has to calculate with 1/4 of the data asx in 4K. But that does not fix this bug.

[alexskunz]

@chico11 obviously it doesn't fix the bug, haha! 🙂 But it's a better workaround for me, because I can keep using my custom monitor profile.

It did make me wonder whether I'm actually affected by THE bug that others are describing. I'm not sure but I would assume that @DYP doesn't appear to be using a Retina/HiDPI display (since he doesn't have the Low Res option for LrC) - and is still affected by it.

That's genius! On an iMac Pro, LR just flies.

Think I'll just keep the setting on forever.

I've been talking to a senior Apple technical support person about this problem today and he has checked the Activity Monitor remotely while I processed an image. I am not a technical person (!) but he said that of the 8.00 GB of memory on my Mac, over 7.00 was being used. Soooo. - does this mean that I will need to buy more RAM in order for LR Classic to function at a speed we are used to? Will that help or not? And is Adobe doing/able to do anything to reduce the amount of RAM being used?

I'm using Big Sur now too.

@ann_chown 

Na, I have 64Gigs of RAM and the speed lag with 4K and custom profiles is there. It is present because the graphic adapter is not requested in library mode at all.

[Was DYP]

Hard to believe that LR would really be functional with only 8GB of RAM. I had a MP5.1 with 48GB for a while and was always running in memory limitation. With 96GB it is much better.

[FeedbackCommunityMember]

Right DYP, I used to have 16GB RAM on an iMac and couldn't have ANY other apps open while running LR, and ran Memory Clean 5 times a day! Now I have 64GB RAM on a 5K iMac and I can read my mail and websites while LRC is still open!

[zobeleye]

with 9.4 the sys runs smoothly with my 32GB. If that is really the case, that the new version needs more than that, then we all have to buy a new M1 mac. I personally find it shocking to consider that they would do such a thing...

[Was DYP]

That is not it. 96GB and I see the same slowness with 10LR. The Library module in LR10 is not using the GPU.

@ann_chown 

As software becomes more functional, it steadily requires more resources. That is just the reality of software. Put 1,000 lbs in your car and notice how much it slows down. 

16GB should be considered a minimum while at 32 it runs really well. There are small improvements with even more. 

And while "genuine" Apple memory is really expensive, there are 3rd parties that make less expensive memory just as good as anything from Apple (never forget, Apple doesn't actually make anything). My favorite is macsales.com, and they include full installation instructions for your specific computer. We've been using their RAM on my wife's iMacs for years with zero problems. 

[COBill]

@zobeleye 

32GB is plenty to run Lightroom well with only modest improvements with more memory. Don't forget what else you might be running concurrently that is using RAM, the machine needs to be sized for all concurrent resource consumption. 

With 16GB on a Windows machine, it runs quite well if only a few browser windows are open (Edge or Chrome but not IE or Firefox) and using Windows Defender instead of a 3rd party antimalware tool.

Lightroom Classic 10.1 brought my iMac late 2015 to a halt and forced reboot, and the crash disabled the Bluetooth keyboard and Magic Mouse II when I rebooted.  I've dropped back to LRC 10.0, which appears to work better.  Also, changed the monitor profile to Adobe RGB (1998) rather than a display profile generated by a colorimeter.  A Windows laptop with 16GB ram and a 4 GB graphics card seems to work better.   Photoshop on the Windows laptop (Dell Inspiron 2018) works fine and also seems to be okay on the iMac.   I've noticed that many of the people reporting problems were on iMacs from late 2015).
