Lightroom Classic: Slow UI when using Mac and Custom Display Profile

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

Just to update my post one month ago…

After trying all advices nothing worked for me.

The only solution I managed is restarting LrC every 20 or 30 minutes, it’s not good but I found it acceptable for my work.

Very recently I did upgrade to MacOs 11.3 but nothing changed.

@joao_ferrand That suggests you may have a different problem, since this bug does appear to have been fixed. Perhaps you could start a new thread describing the issues you're having and including your specs from Help menu > System Info and we can help you troubleshoot further.

Though I think it's possible (without knowing any inside info, of course), that this "fix" is not tested in real world pounding for a long stretch. It's easy for me to freshly launch LR and perceive it to be working; everything fine and snappy. But 500 or whatever high res images (40+ megapixel raw files) later, it's just as likely I'll start praying someone else will make a LR alternative. It usually takes at least a bit of serious work and not casual poking around, to get it to be aggravating.

I do agree that there may be different interpretations of what is 'acceptable' and what is 'unusable'. 10.2 may have been made acceptable for many, but if they use the product in anger for 10 minutes they'd realise the issue re-appears.

Or maybe what I consider to be 'unusable' is fine for many people. In any case, I run courses on LR and I cannot even show attendees how to use the brush control at the moment.

I have started a new thread anyway.

Thank you Victoria, I will follow nick_church new thread as I think my problem is the same, or related.

I will post some more details there and if necessary I will start a new thread.

This is still so painful.  How can a $13,000 Mac Pro be so god awful?  Adobe please figure this out already.  I can use Lightroom for about 15 mins before it bogs down and is absolutely unusable.

Are you macOS 11.2 or newer? If not you are possibly being affected by a memory leak that was fixed with 11.2.

Does that impact Catalina? I have this problem intermittently on Catalina. It varies from excruciating to no-problem, and I can't find any reason, though it is usually, not always, worse as a session with LR goes on for a while.

All software both OS and Lightroom are both up to date.

@Chris Hood Totally agree. I have spoken to Adobe who claim there is no issue reported on this. 

pretty outrageous really!!!

I have found the latest MacOS to be slightly better, but honestly, when doing a professional edit at speed it is carnage. So slow.

It's absurd. This computer has been out for long enough now there should be a legit fix.  So frustrating.  My 16" MBP is faster and more useable than my New Mac Pro and that sholdnt be the case.

Adobe please fix lightroom for us New Mac Pro users and not just a temporary fix that seems good while on the phone with tech support but as soon as you actually dive in and start working it goes back to complete shit in no time.
