P: Slow UI when using Mac and Custom Display Profile

Thanks. Did you try the sit for 5 minutes I suggested? What happened? 

Have you tried a monitor recalibration to see if a new profile exhibits the same slowness as the Cal1 profile in your video?

@Rikk here you go... https://www.dropbox.com/s/lkopk936osx4ohc/lr-sluggish-publish-collections.mov?dl=0 

Have you checked the Lightroom Queen website? Her articles persist and are updated whereas burying technical info in  forum threads works poorly. 

I have a pretty hefty set of Publish services and am not experiencing any issue.....

Can I go slightly off topic and take a poll as to where to find the definitive list of steps to take to optimize one's catalog for best performance?

I am not seeing it on my machine that had the issue previously.  I am hoping someone with a robust set of Publish Services can give me a second opinion.

If you go to Publish Services and just sit for 5 minutes is the scroll any better? Worse? 

And, yes, as always videos of the issue are great. We may want to start a new thread for this as it seems outside of the prevailing experience. 

And an update - I discovered that sometime in the past I must have set standard previews to 2880 instead of Auto.  I plan to rebuild them all overnight and see if that helps.  There goes the free space on the drive 🙂

@Rikk Exactly the same behaviour as we saw in the library grid view before - unresponsive, laggy scrolling, etc. 

It's wonderful in folders and collections, just not fixed in publish services. 

Fine with sRGB screen profile, useless with the custom profile ... as before.

I'll record it if it helps - let me know if you want that linked here or elsewhere... 

@Barrie Spence 

Can you elaborate on the Publish Services issue?

Well, all bets are off when running unsupported configs.  Can you replicate the issue on a non-hacked system?
