P: Slow UI when using Mac and Custom Display Profile

Note: I am closing this conversation as it is becoming a catch-all for performance complaints and this specific issue is resolved.

There IS a problem here however, and with a career running a software testing company, it's rather frustrating to be told by Adobe that there is nothing wrong. 

Here is the thread that describes the issue people are seeing: https://feedback.photoshop.com/conversations/lightroom-classic/lightroom-classic-slow-and-stuttering-on-new-topspec-imac/608fcedaa8e98c342a7a9b39

@Chris Hood  This specific issue is already fixed and confirmed by those on the thread.  Since your current issue does not relate to this thread, I would recommend your posting on a thread where active participation from engineering is happening germaine to your current issue.  It would be more useful to include actual data rather than vague descriptions.

Example:

At startup, it takes the exposure slider no time to update the screen - 20 minutes in it takes 3 seconds.

or

At startup Exporting 50 images takes 2 minutes and 30 seconds- 3 hours in it takes the same images 25 minutes and 15 seconds.

Lastly, actual version numbers of your OS, Lightroom and specific specs about your computer are always helpful necessary.

Here is an example thread that might apply to you. https://feedback.photoshop.com/conversations/lightroom-classic/lightroom-classic-slow-and-stuttering-on-new-topspec-imac/608fcedaa8e98c342a7a9b39  Read it and if it matches your system's behavior, consider posting there. 

Thanks!

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.

@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. 

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

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.

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

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.

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.
