P: Slow UI when using Mac and Custom Display Profile

Another thing you may want to try is I uninstalled and reinstalled LR and then built a new monitor profile and that seems to have fixed the problem.

Of course not, but it's the IT guy's fallback: a workaround to get you working (until it gets fixed)!

*carlos_cardona Jepp, but this cannot be the answer. Because it is a photo editing programm you need to work with the right colors on your monitor.

Did everyone read about NOT using the calibrated ICC color profile on your monitor, but selecting one of the built-in profiles (like the Apple RGB profile on the Mac?) chico11 says "20 times faster" with V10!

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:

I have now used 3 different programs for profiling. i1profiler, ColorNavigator and Basiccolor display.
The same result with all of them. The error can be clearly and unmistakably attributed to Adobe. It is a shame for this company to create a broken workflow for its customers.

And btw. it is NOT a problem with the hardware like bill_3305731 mentioned here.

We hope that a new version will appear soon. Unfortunately we are now working with a 9.4 version on one Mac and with the V10 on the other Mac. The upgrade was carried out automatically (we immediately deactivated the auto update). Since we have already processed some jobs with the new version 10, we unfortunately have to finish them with the V10, which takes a lot of time. We are currently processing new orders again with V9.4, it is extremely difficult at the moment and working is becoming a challenge!

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.

Is it possible to roll it back with the catalog from 10? And what is with Indesign or Illustrator? and the question is, What the hell is Adobe thinking about publishing such software? 

Adobe is working on it. For now either stick with 9.4 or wait for the fix.
