P: Slow UI when using Mac and Custom Display Profile

After updating to V10, we cannot work smoothly in Lightroom at all. It takes 3-5 seconds until the photos in the library and in the develop module are loaded with all settings. The scrolling through the thumbnails in the library is awful! Our catalogs have a size of 1000 to 4000 photos, this makes no difference!

We work with several MacPro and had no problems with version 9.4:
MacPro (Mid 2015)
2.5 GHz Intel Core i7
16 GB 1600 MHz DDR3
Intel Iris Pro 1536 MB

MacPro (2018)
2.6 GHz Intel Core i7
32 GB 2400 MHz DDR4
Readon Pro 560X 4 GB
Intel UHD Graphics 630 1536 MB

@lewis_kemper It's not the solution. They are debugging the problem. I'm sure they'll resolve this shortly.

So Adobe's solution is for use the abandoned our custom monitor profiles and work in an non icc environment with uncalibrated monitors?  That's a BS solution.

I just had a support session with Adobe - thanks for investigating!

The expert suggested changing the color profile and it made a night&day difference. I'll continue monitoring in the next days, but this seems to be the culprit at least on my machine.

I uploaded the icc profile that seems to cause this issue here:

It was created by Apple and was selected by default on my MacBook Pro.

I made a video where i show the effect. It is in german, but you can see which profile i use and which impact the changing of profiles has.

Same with me. spinning wheel all the time, makes almost impossible to work like that. Super frustrating 

I have the same issue and need a fix.

Upgraded to LrC 10.0 release with camera raw 13.0

on new Apple Macbook Pro ( 16-in 2019) 2.3GHZ 8-core intel core i9  with MacOs Catalina 10.15.7 with graphics being

AMD  Radeon Pro 5500 4GB, Intel UHD graphics 1536 MB

Machine has 16GB Ram.

Systems: load catalog slow, takes ages to scroll and display.

What is the problem?

Previous version ran very well, I am also very happy with performance using Da Vinci Resolve.

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 with the profiles from calibrated monitors.

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

Same problem here (MBP2020 10th Gen Corei5, 16GB, Catalina, Lightroom V10).

Can you please fix this, Adobe?

Happy To!

Here you go....

Let me know if I can provide anything additional to assist in resolving this!

Strangely the spinning wheel shows as a pointer cursor in the movie.
