P: Slow UI when using Mac and Custom Display Profile

Tremendously relieved to see this update! My app just updated. Overall much better, but still a bit choppy when in full 6K on the PD XDR, and the thumbnails are set to a larger size. This is on a Mac Pro 2019 with W5700X with 16GB of   GPU RAM and 80GB of system RAM

Additionally seeing scroll lag on the sidebar of the develop module. 

Hallelujah.. That was a painful journey! (The thread..more so than the actual issue)...Thanks Rikk!!

Updates to Lightroom Classic and the Lightroom Ecosystem products for Desktop, Mobile and Web were released today and contain a fix for this issue.

Please refresh your Creative Cloud application and install your update when it becomes available. Thank you for your patience.

Oh of course what was I thinking: Adobe and their software team deliberately produce bugs to upset you. 

Do your duty: Pull out your checkbook and call your lawyers.

Oh, and they do have a solution.
Wait for it....wait for it.....

I simply cannot believe the level of unaccountability I'm seeing from people on this forum. 

Let's pretend your Uber driver picks you up, and the next thing you know you're in an out of control vehicle, that eventually crashes half way to your big business meeting.

After the crash, you get into another Uber, and the driver tells you:

"Your last Uber driver was having problems with the brakes on his car all day. He didn't know it when he left the house, but if you would have read his recent reviews you would have seen that other customers nearly died making it to their destinations. You should have looked that up before you got in his car. Sorry you missed your meeting and lost a $50k contract, hope you at least have medical insurance. You really should have your own mechanic look at these cars before you get in. The EULA says you can't sue. You should really know better."

THAT is exactly what I'm hearing from people on here. The lack of accountability is just mind-boggling. 

Turns out I AM an ACTUAL "beta tester". SIX MONTHS after the software was released, and at least 5 months from what I've now seen on the internet, the problems have been known. They STILL are not warning anyone of the potential problems at the point of choosing to download. 

Beyond their duty to provide a working product, they have a duty to warn people of the harm their software may do once they know of the problem. The fact that they STILL do not have a solution, and are not communicating AT ALL about the problem is total corporate malfeasance. 

"Gotcha with my EULA, sucker" is not a good look, ever. They are earning every drop of vitriole they get.  

You are being absurd. 

Adobe has a contractual obligation to deliver the product I am paying for. It's a basic principle of contract law, summed up as "getting the benefit of your bargain". 

THEY agreed to deliver a working product. THEY failed their contractual obligation, bigly.

They also did not, and still have not given users ANY reasonable warning of defects that they (a) know about, which we *know* because they say they are (b) trying to fix the problems. ZERO help, ZERO warning, ZERO communication about a timeline for a solution, and almost ZERO meaningful communication about how to work around the problems (you have to exhaustively search just the right terms, like I had to, and then you *start* to find the bread crumbs)

They should be refunding subscription payments until a fix is effected. They should warn people not to install the software if the known defects might cause a problem for the client. PERIOD.

Instead, all the managers at Adobe are sitting at their desks polishing their participation trophies while talking about their golf handicaps, instead of warning hard-working customers about their software handicaps.  

This whole situation is absolutely outrageous. There should not be this many very basic problems, and since there are, there should be communication from the company who entered into the contract agreement with ME, to prevent further damage to ME, but there has been NONE. 

It's seriously incredible that people are sitting here telling me that people should never trust a company to provide the goods or services they are contractually agreeing to provide, instead citing 'you agreed that you can't sue them in the EULA', and thinking that people are essentially paying a monthly subscription to play software-russian-roullette. You people apparently to not understand the basic tenets of a contractual obligation, much less the common decency that should - by any reasonable standards - demand that people be given a meaningful warning about any one of the multiple known deficiencies and subsequent workarounds or even a timeline for a fix. 

Adobe is run by people with participation trophies on their desks. 

They knew or should have known of these problems in beta testing,

Again, no.

Take it from an actual beta tester.

Period.

I wouldn't define 'waiting two months until the first update is released' as "rushing ahead". 

They knew or should have known of these problems in beta testing, and from what I've finally found on the internet, the very serious and basic problems involving using GPU acceleration, custom monitor profiles being incompatible with PS and LRC, and gorging itself on RAM until it crashes the whole system were in fact known to them. 

It was also known to them that once you update the catalog to LRC 10, you cannot easily return to the functioning version 9 of the program. 

It was also known to them that users were downloading and installing the program update without knowing any of these things, and they sat there in their pee pants not saying a word, sending people blindly into a wholly intractible, and practically irreversible downward spiral. 

They knew, and they said nothing. Much like Boeing knew about the problems with the 737 MAX, Ford knew about the problems with the Pinto, the Explorer, etc. 

It is NEVER the job of the customer to extensively beta test software they are paying for. The software industry has been getting away with these things for a long time, and the number of issues with this release are way beyond 'reasonable'. They rushed the release to coincide with their annual Adobe festival, and were too irresponsible to even warn people of their failure. 

It's inexcusable. 

It would be one thing to have bugs with the new M1 chips and Big Sur, where it's all very new, but the litany of failings with this release are happening on a wide array of operating systems and Mac computers. It is not limited to 'new discoveries with a new OS or new M1 hardware. 

They should have, at an absolute minimum, warned their customers of the peril they were headed for. Period.
