P: Slow UI when using Mac and Custom Display Profile

Hi Victoria

- attempted performance improvements
- modification to foundational code 
- bigger team

Are these official information from Adobe?

> We have seen a steady degradation in software quality and performance and speed of resolution of issues since they announced the cloud version after many years of steady improvements.  That's a clear indication that resources have been shifted from the desktop product towards the cloud version.

@mountaingoat A slightly different perspective... looking at the performance improvements that are being attempted, the engineers are being allowed to mess with foundational code which hasn't been touched for years, which sees bigger performance gains but also risks bigger bugs like this one. The engineering teams are bigger than they've been for a long time, but they're tackling more risky stuff.

THANKS FCbee That was easy!

(sorry for off topic post). As interesting as this may be I'd like to turn OFF EMAIL Notifications, in fact they are all unchecked in my profile BUT I am still getting the Notifications via email AND there are a lot of them!. Can't seem to stop them. Any suggestions welcome (link to "how to unfollow/unsubscribe" from this thread would suffice. I can't find the button anywhere to do that.

I wrote too soon. Redoing the calibration did not solve the problem. In my case, 16" Macbook Pro, Lightroom gets slower the longer I use it. I haven't used it long enough for it to turn to glue without quitting it, today, but just now it is slower than I am. I go to do something, but Lightroom is behind me. This is on an otherwise fast and capable computer.

Also, you don't have an IT Department. Did you ever see a corporate computer user without an IT Department (onsite or off)? You are your own corporation, get an IT department! If I was your IT, (and for 25 years, I was a Mac IT Pro), you would NEVER have moved to either Big Sur or LR Classic V.10...yet. Be conservative in your device upgrades, look hard before you leap!

Also also: NEVER use Auto-update, turn that feature off in Creative Cloud. Wait until you get the "all clear" from Jeff Harmon (Photo Taco Podcast) or Victoria Bampton (lightroomqueen.com) that it's OK to upgrade. Same with your MacOS, listen to The Mac Observer's "The Mac Geek Gab" podcast (or read the website). I'm still on Catalina, I NEVER upgrade until the ".2"  “.3” version, giving Apple time to squash the usual bugs.

This was an introduced defect that could have been resolved by reverting to the previous code, but it wasn't.

What code specifically (and from what experience with Adobe's code base)? 

You either test the heck out of it, or have a really good reversion process (or both).  

Which is what was done, without utter perfection. However, unlike many software products, perhaps ones who's code base you have actually seen, there are tens upon tens of thousands of customers using LR, on a heck of a lot of hardware and versions of OSs, some a moving target.

Adobe is clearly moving their code to cloud. 

Specifically what code is that? Does the code once moved to the cloud become variant and buggy? 

And it is yet another flashing red light on the dashboard for Classic's long-term future.

And it is yet another flashing red light on the assumptive dashboard for any product you don't control; long or short-term future.

I'll ask again: What software product do you recommend that is demonstrably bug free? 

Yup, and that's when the thread really heated up.   This was an introduced defect that could have been resolved by reverting to the previous code, but it wasn't.  Adobe has never been a company to admit a mistake and quickly revert when things break, so fair point, we shouldn't expect the leopard to change.

To be more crisp:

External issues:  The 16" performance issue was new - apple released a new piece of hardware.  The iOS import failure bug was also new - apple changed iOS.  Fine, both of those suck, but aren't adobe's fault. Understand if that takes time to fix.  Don't like it, but understand it.

Internal issues: The slideshow bug and this bug were introduced by Adobe's failure to properly test their software prior to release.  These are directly at their feet - it worked, and now it doesn't.

I've built both commercial and enterprise software.  You either test the heck out of it, or have a really good reversion process (or both).  What you don't do, if you want to keep your customers, is neither.

Adobe is clearly moving their code to cloud.  As part of that they're clearly shifting staff to the new platforms and are resource constrained.  It's why fixes take a long time, so it's even more important that they fix the process problems causing them to break things.

And it is yet another flashing red light on the dashboard for Classic's long-term future.

FWIW, there already has been an update (Lightroom Classic 10.1.1 in mid January) released that did not address this issue.
