P: Slow UI when using Mac and Custom Display Profile

I do agree that there may be different interpretations of what is 'acceptable' and what is 'unusable'. 10.2 may have been made acceptable for many, but if they use the product in anger for 10 minutes they'd realise the issue re-appears.

Or maybe what I consider to be 'unusable' is fine for many people. In any case, I run courses on LR and I cannot even show attendees how to use the brush control at the moment.

I have started a new thread anyway.

Though I think it's possible (without knowing any inside info, of course), that this "fix" is not tested in real world pounding for a long stretch. It's easy for me to freshly launch LR and perceive it to be working; everything fine and snappy. But 500 or whatever high res images (40+ megapixel raw files) later, it's just as likely I'll start praying someone else will make a LR alternative. It usually takes at least a bit of serious work and not casual poking around, to get it to be aggravating.

Thanks Victoria, new thread started here: Lightroom Classic slow and stirring on new, top-spec iMac

@nick_church_hbl0zc9vlqwo3 If you're on 10.2, continued issues would suggest you have a different problem. Can I get you to start a new thread and include your specs from Help menu > System Info please, and we'll see if we can help you investigate further.

@joao_ferrand That suggests you may have a different problem, since this bug does appear to have been fixed. Perhaps you could start a new thread describing the issues you're having and including your specs from Help menu > System Info and we can help you troubleshoot further.

Just to update my post one month ago…

After trying all advices nothing worked for me.

The only solution I managed is restarting LrC every 20 or 30 minutes, it’s not good but I found it acceptable for my work.

Very recently I did upgrade to MacOs 11.3 but nothing changed.

@jlehet This is exactly my experience!

It's funny, for me it is sometimes slow and sometimes snappy. I can't find any relationship to any variable I can understand, though it seems to get slower the longer I work, and especially if I've been working it hard. Restarting LR seems to help quite often, but that's obviously a hiccough on workflow. It's pretty common for me to be a couple of steps ahead of the app in my workflow on a modern Mac with plenty of RAM. I'm doing things and LR is lagging my actions. Still. Current version of LR, Catalina 10.15.7. I've been using LR since the beta, before v1, and v10 is the worst. I wish I had stayed with 9 but it's too late now.

It’s so frustrating. It can work fine for 10 mins and then local adjustments, particularly the brush, become unusable. 

When I look at Activity Monitor nothing is using the CPU or GPU and there is tonnes of memory left so it’s baffling what is going on. 

my workflow on the current edit is:

- Use GPU for most of the edit as it’s so much more reproduce when changing sliders. 

- If If i need to do brushing, then turn off gpu. This releases the brush cursor, so at least you can move it without glitching. The effect of the brush lags way behind so it’s still not ideal.

- Every now and then i will restart lightroom and give myself the luxury of 5 mins of perfect performance before the nonsense all starts again.

Hi Nick, I’m in the same boat.

Same Mac. Same job.

I’ve been experiencing serious issues with LRC and Photoshop for months now, with no fix or useful feedback from Adobe or Apple.

My workflow has ground to a halt, seriously affecting my work.

I’ve been using Macs and Adobe for years and years, and am totally dependent on them for my business.

I’m at a loss to understand how and why they can allow this to happen in the first place, and to then offer no help, no solution, no apology.
