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.
Agreed! Slow to the point of unusable. I guess I'll try rolling back to the previous version.

I use a calibrated monitor too on my Macs, and I do not see any problem like that. Do you know how the profiles were created, and especially in which ICC-version? You can save a profile in V2 and in V4. As V4 is newer, a lot of people think it must be better. In reality there are quite a few applications that have problems with V4 profiles (and at least in the past Lightroom was known to be one of them), so the advise is to stick to V2.
ICC Profile v2.2 makes no difference. This is what I set in ColorNavigator. And Gamma 2.2 and no L*.
What software do you use to make your profiles?
Mac or PC?
What do you mean 'Mac or PC'? Your problem is on Macs and I answered that I use Macs too. I make my profiles with i1Studio. I really do not see any lag in the Library. If I set loupe view to 100% then I can move the image as fast as I can move my hand.
BTW, did you report this in the appropriate forum? This is a user-to-user forum. I also saw your post in the LightroomQuenn forums. That is a user-to-user forum too. If you want to report a bug, go to https://feedback.photoshop.com. Search for the problem first. Somebody else may have already reported it. In that case, add your vote and do not create a new thread about the same problem.
This answer is intended for those who might suspect that it is an error in the profiling software:
If I use i1profiler to build the profile as version 2, the result is the same. Unusable software from Adobe.
