Lightroom 3 Freezes On Dust Spot Removal

I am going through a 300 old photos that were scanned to .jpg files and cropping/adjusting the photos to create a DVD slide show. When I first started, Lightroom locked up a couple times using the dust spot removal tool. The cursor was a closed hand and nothing responded. After killing the app a couple of times, It was working for about a hour, and then started having problems again. When I clicked on the spot removal tool, the cursor stayed as a closed hand. I quit and came back it. The spot removal again locked up the application. It seems to happen on larger spot removals. Trying to modify the large spot removals also causes Lightroom to hang up (last time was with a resize cursor).

I am running the 64 bit version on Windows 7 Professional, 6GB Ram, Quad-Core, no other programs running. My 300 photos and catalog (with ony these photos in it) are on on an Solid State Drive. I am using duel monitors with duel ATI Radeon HD 4600 1GB cards.

Does anyone know if Lightroom 4 has solved this issue? If it has, I will upgrade. If it hasn't, Adobe can go fly a kite.

Are you running the Beta or do you have the Release version of LR4?

Wow, almost two years after the original post and still this glaring bug still hasn't been fixed. My opinion of Adobe is a lot lower as a result. Why pay Cadillac prices for Yugo quality?

kend99,

Which version of Lr are you using? Becausein Lr 3.6 this "glaring bug" has been fixed.

Also, in retrospect I have to say he following:

I am now using Lr 3.6 64-bit, and have 12 GB of Ram. And now the dust spot removal is blazingly fast.

So my verdict is: this was never a bug in the strict sense but the dust spot removal required lots of RAM and processor power. On systems with "only" 2 processors and 4 GB of RAM or less the system was just overburdened.

I'm using LR 3.6 on a Win 7 x64 machine with an Intel i7 processor, 6 GB of RAM, and a Radeon HD 5650 video card, so it's neither an old or underpowered machine.

I can reproduce the bug 100% of the time.

I'm glad to see it's not just me. LR used to lag here and there on my old computer, but I built myself a new PC a couple of months ago, it's a good computer overall, good CPU, 8GB memory, even using an SSD for system drive and a RAID 10 for work/storage, generally LR flies like the wind, with one exception; Spot Removal. I would say about 40% of the time I have no problem here either, but about 60% of the time it lags and stutters when doing spot romval, sometimes to the point of freezing the computer for a couple of seconds.

I found it strange that we're at version 3.6 and Adobe STILL haven't managed to iron this one out.

But at least I'm not alone, so I'll try to find a little comfort in that.

This is because nobody who can really fix the problem reads this forum.

From mulitple experiements of my own and from other people who contributed into this discussion, it is pretty obvious: Lightroom Spot Removal has a problem with the Core i5 / Core i7 CPUs when Hyperthreading is enabled.

Disable the Hyperthreading feature in your BIOS (sometimes also called virtual cores) and you will see the difference.

Now all is left to do is to open an official support ticket and point to this thread and to this post (and then wait for version 4.x) :-(

I am not sure if I will ever buy something from Adobe again.

Was done already, see my prior post.

The problem seems to be related to multiple cores, and can be avoided by setting processor affinity to 1 core for LR (done in TaskManager).

I thought I'd add a couple of thoughts as this thread has been very helpful, thank you all.

I am running Lightroom 3.5 on Windows Pro 64bit, Intel i7-740 with 8Gb ram. Was having this problem on one particular Tiff file. Lightroom behavior was also slow generally.

Found that if I used the 'Show desktop' button at the bottom right of the screen this minimised Lightroom which then unlocked in about 5-10 seconds but had not done the edit.

Using the 'Set CPU affinity' worked for me. In my case I have set it to 4 and it appears to work fine now.

I have come across something similar when setting up fast boot and the number of cores it is to use.

In system information it shows that my processor has 4 cores, but elsewhere it shows and logs 8 cores.

I believe there are 4 real cores and 4 virtual cores, problems seem to occur when using the virtual cores..

I'm glad I found this thread. LR was driving me mad with this. I have an I7 980 Extreme 6 core CPU and nVidia card. Since I use Nik from LR I often am working with TIFs, and spot removal can lock up LR for 10 minutes at a time!

I tried the affinity workaround and it seems to help. But indeed, why would I want to slow LR down by using only one core? Adobe, fix this! Not everyone finds this thread, and you are frustrating users and losing face.

It does hurt something else - multitasking performance of Lightroom as now there is only 1 CPU core is available to the application.

It is very apparent if you need to export lots of photos and do some other work at the same time (inside the Lightroom I mean).

It will not hurt any other application or the operating system.

Can I ask everybody affected to open support case with Adobe?

I will do the same in my spare time.

According to this thread, this problem has been going on for 5 years?! I'm running LR 3.5, Win 7, 64 bit, i7, 4 gigs of ram, nVidia GeForce GT 540M video card - don't remember having this problem before, but lately the spot removal tool totally crashes the program - have to go to task manager to close/reopen/try again. end up doing edits in PS - no fun! Please Adobe - fix it or give us a workaround!

Otherwise I love love love LR!

It looks as if this forum had been created for the affected users to share their frustration with each other. The problem has been there and has been untreated for far too long.

Clearly the problem mostly affects people with the latest i7 / i5 CPUs and it has to do something with multithreading because my fix suggested above helped many people (not only on this forum).

Has anyone actually tried to open a support ticket for this issue with Adobe? Should we start an on-line petition? It is really ridiculous situation that such a "flagship product" has such a serious issue that makes it virtually unusable in many cases.

Whoa fe-dot - resetting that channel as you suggested (Launch Lightroom and then open your Task Manager, go to the lightroom process, right-click on it and "Set Affinity" to 1 core only (pick any).seems to have done the trick - hopefully it didn't hurt anything else - will post here if it does... Thanks so much!

Another REALLY maddening thing is that I need to redo it EVERY FREAKING TIME I open LR... argh!

Yes, a petition is indeed in order - I have not submitted a support ticket - anybody else??

I've just updated to the latest 3.5 version...

I'm running an AMD x6 system with 12 Gig's of RAM.

The problem is indeed within Lightroom itself.. even if i run light room on seperate core's of my processor, only one hangs on 100% when using the spot removal tool.

most annoying is that lightroom totalloy hangs instead of the spot removal function itself. (guys! run it on a seperate processor!!)

i discovered that it is pure a calculation loop that its hangs in. well i figured that that must be it.

some pictures i have no problem but other pictures not even the first attempt to heal something.....

if you have a picture with only white, it goes ithout any problems but if you use a picture with grain in it.. it really a pain in the ass...

i can only figure that the differance is that it is much more difficult to calculate en render the the heal colours for a picture with grain. (no definite colour range)

and that the module for spot removal hangs on that.

if it is pure calculation power that is the issue, GUYS make sure LR really uses all of my 6 cores!!! or rersve some for calculation and the rest for the gui.

PLEASE DO SOMETHING ABOUT IT ANYWAY!! THIS IS AN ISSUE SINCE VERSION 3.0!!!!!!! NOW I THE LATEST 3.5 VERSION! we are using it for our work!

I get the same problem (i7-930, 12G RAM, W7 64 bit, Lightroom 3.5), but it's intermittant.

For example, a few days ago, every time I tried to add a spot removal, it would hang for minutes (usually until I killed it). Restarting LR made no difference; more spot removal edits on the same image would hang. But today I've tried on several images and response is instant, however many changes I make or new spots I add.

Simon, I wonder if the difference has to do with checking or not checking the "Enable Profile Corrections" box in the Lens Corrections Panel. I've found that checking this box can seriously slow down performance, especially with the spot removal tool.

I'm having this same problem with both 3.3. and 3.2 (which I downgraded to in the hopes that it would solve this issue, which it didn't). Everytime I use a touch-up tool, it freezes LR, either for a few seconds or permanently, so that I can only quit the program via the task manager. My desktop is less than a year old and has more than enough resources to run this program, so I doubt it's a hardware issue. (I'm not really sure why this has been marked "possibly solved" - it clearly hasn't been for a lot of users.)

System specs
Windows 7 Pro, 64-bit

i7 930 @ 2.8 Ghz

12 GB Ram

4 TB harddrive

So glad I received my copy of LR as a gift, since I would really be annoyed if I'd actually shelled out money for the program as this bug has apparently existed for nearly a year.

@Komboloi:

Well summed up. Unfortunately I paid for it. This is the first Adobe product I purchased and now I am really frustrated.

LR 3.4 RC just came out and there is nothing in the release notes to indicate that this issue is even recognised as a problem.

Just like you I have Win7 64bit running on i7 CPU.

Can you try this and see if it works for you. Launch Lightroom and then open your Task Manager, go to the lightroom process, right-click on it and "Set CPU affinity" to 1 core only (pick any).

See if this changes the behaviour.

Sure thing - I'll give it a try as soon as I get home.

Mine actually did that once but maybe because the brush was too big....but it literally crashed my whole laptop--ended up costing me $300 to repair and all data on the hard drive could not be recovered Ohhhh LR!!
