Lightroom Classic 8.0: Almost unusable with multiple problems

Multiple issues since update to LR Classic CC 8.0.

I updated when the update was released - I have a Fuji X-T3 and was happy to see new camera support added.

Since then, LR is so slow as to be almost unusable:

- when switching between Library and Develop mode, screen often goes white
- histogram takes a long time to appear, and often says "calculating"
- LR needs to be force closed repeatedly because it will not respond (and it slows down the entire computer)
- CPU consumption spikes erratically when LR is open, with LR going from approximately 5-90%, even when open and idle


I contacted Adobe for support via chat (and subsequent remote control). Case # 
ADB-4164592-M8L1 . After almost an hour of troubleshooting, agent told me that 8.0 had known issues and to roll back. I don't want to do this because I want the X-T3 support. Agent tried clearing cache and video cache. Each time, the cache would not clear and LR had to be force killed.

I also took the following steps, as suggested by an Adobe Digital Imaging Advocate, to no avail:
Close Lightroom
Restart the computer
Use the Adobe Creative Cloud App to uninstall Lightroom Classic CC
Restart the computer
Install Lightroom Classic CC via the Creative Cloud App
Restart the computer
Launch Lightroom
Wait 5 minutes

I need some help here , please.

Greetings giseled,

I am sorry for the issues you are having. Are you using a Mac or Windows machine. What is your OS version?

I'm on a MacBook Pro, running High Sierra 10.13.6, with a 3G Core i7 processor and 16GB Ram

Without knowing what OS you're using, no one can be definitive.  However, I run LR8 on a MacPro with Mojave and 128GB of RAM.  I find that LR8 will gobble up 95GB of RAM whilst doing an Import/Preview Build which shows no progress.  I have to frequently use Clean MY Mac X to release the memory and get LR8 to go back to work.

If it wasn't for Loupedeck+ I would go back to LR6.  LR7.5 to LR8 have been a huge disappointment as far as performance is concerned.

Giseled,

I don't see a preference file mentioned:

A Preference File will survive a Lightroom uninstall/reinstall. Sometimes weird behavior is corrected/cured by resetting the preferences. 

Reset Procedure:

1. Close Lightroom.
2. Hold down [Alt/Opt]+[Shift] while restarting Lightroom. 
3. Overwrite the Preferences when prompted by the dialog.
4. Close Lightroom.
5. Restart Lightroom.

Does the behavior continue after resetting the preferences?

Thank you for the tip. I am heading out for a few hours, but will try this when I return.

I tried that, and it's still pretty slow moving between modules and displaying the histogram

Poor performance is NOT weird behavior; it's poor programming and a demonstrable lack of software engineering practices.  Resetting the preferences is not the answer in these cases (though it will certainly work when the preferences become scrambled or corrupted through an upgrade or use).

Giseled,

Since we've checked the preferences and you've done a clean reinstall, let's look at your configuration.

GPU (Checked or Not)?
Location of Catalog?
Free disk space at location of catalog?
Location of images? (describe the drive hardware)
Number of Monitors active
Resolution of Monitors
Video Card specs

Status of Lightroom 7.5 -(installed or not)

GPU (Checked or Not)? - where do I find this? If under "preferences", "use graphics processor" is checked

Location of Catalog? /users/(name)/pictures/lightroom

Free disk space at location of catalog? 66GB

Location of images? (describe the drive hardware) external 5TB HD

Number of Monitors active - sometimes one (retina display on macbook pro - 2560x1600), sometimes external monitor plugged in. External monitor is 1920x1080 res

Resolution of Monitors - see above

Video Card specs - not sure where to find this on mac. If it's under "about this mac", it says Graphics Intel Iris 1536 MB 

LR 7.5 uninstalled.

Looks like this is linked to the issues I'm having after clearing some caches. Perhaps it's not that after all.

I too am suffering with huge amounts of RAM usage, and completely slowing to a halt.

I have tried resetting preferences and rebuilding syncing data, but without any success.

Today I left Lightroom Classic running on my Mac (running Mojave) while I was at work, but with syncing paused, and I still found it had frozen, and using more RAM than I have installed. I hadn't even applied any edits or anything like that.

Looks like a massive runaway memory leak or something.

Cheers,

Andy.

Lightroom has almost always had some issues with memory leaks, but with LR7 and LR8, it has become far worse, beyond the ability of Mac OS X to accomodate through its standard 'garbage collections' processes.  (Windoze does not have this facility as Bill Gates said it was never necessary.)

I too can leave LR8 doing nothing, not even writing to XMP files in the background, and by morning it will have gobbled up as much as 95-98GB.

When it's working, I have to clear memory in order to get LR to come out of its stall.  Memory Clean will oft times notify me that "Lightroom is inactive and you can clear nnGB of memory by stopping it" where nn is lots of RAM.

Poor programming effort by Adobe.

Pretty much unusable now. Every time I leave it dormant, I come back to find it consuming increasing amounts of RAM, and beach balling. It can be quit, if you can wait many, many minutes for a menu to appear, or for Command-Q to work. Force-Quit usually works OK quite quickly.

So far now I have tried:
Rebuilding Syncing Data
Resetting Preferences
Uninstalling and reinstalling Lightroom.

I'm very reluctant to try deleting CC web data, as the problem occurs even with syncing paused, so I think this is more a localised problem.

Performance should not be an issue, my system isn't new, but is no slouch either:
Apple iMac (Late 2013) 27" 3.2GHz Quad Core, Nvidia GeForce GT755M 1GB, Crucial 500GB SSD (250GB free) where the catalogue is. My photo originals are on an external 3TB HDD (partitioned to 1.3TB for the photo storage) connected by FW800. GPU Support is ON.

Until the last few weeks this has proven to be a very well performing setup for editing and managing my photos, and I have rarely, if ever, noticed any of the lags that others have found with more powerful, or newer, hardware.

The issue is occurring with Lightroom running, but idle (even in this state it continues to eat up more and more memory), so there is a very bad problem somewhere.

Agreed.  I have these issues and I don't sync anything to the Cloud any longer (and even then, it was only a single folder of favorites to show clients, friends, and models my portfolio.)

GPU support can be ON or OFF, machts nicht.  I can have LR open on a monitor, be working elsewhere, come over to LR, and be greeted by the rotating beachball.  Infuriating!

The so-called Holy Grail of resetting LR preferences make no never mind.  LR 7 and LR8 are memory hogs...pure and simple.

Andy, I would love a few screen grabs of your Activity Monitor - say 5 minutes after launch, an hour after launch and then one from a long idle period if possible.

Hi Rikk,

Thanks again for responding.

Here are some screen shots of Activity Monitor.

The first one is after a few minutes running:


The next is after only 9 minutes:


And the last of after a day at work with the computer left to idle:


I hope that's of use to you.

By the way, I have also tried reinstalling Mojave, and I tried the permissions adjustments someone else suggested. I've also logged out and into my account, and rebuild the sync data again. Nothing is helping.

Regards

Andy

Andy, 

Thank you for the Activity Monitor timeline.  That is not normal behavior.  You keep mentioning rebuilding the sync data. Does this rampant memory usage only occur when sync is active? All the time?

My activity monitor looks similar to these screenshots. I still have to force close repeatedly due to beachball/not responding.

You are consuming a lot less memory than Andy so I suspect your two issues are unrelated. He gets to 28 GB and becomes non-responsive.  You are getting to a non-responsive state much more quickly.

I've completed all troubleshooting steps and nothing is working. Rikki - can you please work with me some more or have this issue escalated?

Thank you. I had surgery on Friday and recovery is slower and more intense than expected. I'll be in touch in a few days to continue troubleshooting.

I have posted to LR forum "Lightroom Impossible to Use" I get a spinning color wheel after 5 minutes on Mac Pro Mid 2010 12 core running OS 10.14.1 with Radeon RX 580 8192 MB graphics card. Already did all that was suggested. Had no choice but to move catalog & photos to Mac Book Pro (LR runs fine there). Do not want to re-sync all my collections as I will have to generate new URL links. Am hoping Adobe finds a fix as I have been a LR user since its creation & this is a MAJOR issue.
