Hello,

Since Adobe chat can't help me (the engineer just closed the chat because he simply didn't know anymore what to do?) I'm asking here for help.

I've used Lightroom for a while, but had issues with slow responsivness, sometimes crashing etc..

So I installed 2 weeks ago Lightroom Classic, but it has more or less the same issues.

It is slow, not so responsive and sometimes my screen flickers, go dark, photo's freeze during post processing in pixels, .. and exporting is after 10 sec freezing and LRC is crashing.

I have a performant system:

- AMD 5800X3D

- 32 GB ram 3200Mhz

- Nvidia 3090 24GB

- W11 2H22 all updates done

- drivers of all components are up to date

Someone that had semiliar issues and can point me in a direction? Not the standard things like, updates, reinstall GPU drivers, ...

I used LRc on way less performant systems, and it worked like a charm. I don't know what is going on.

Hate to say it but this really does sound like a hardware issue. I would first suspect the GPU. First thing to try is to turn off the GPU in Preferences->Performance. This unfortunately due to a bug in the latest Lightroom 13 does not turn off the GPU for exporting but at least you can see if it no longer crashes in post processing. It will be slow but if it still crashes your hardware issue is elsewhere and at least you have that eliminated. Lightroom really taxes all parts of people's systems and often hardware issues only show up in Lightroom simply because it taxes it in ways other software doesn't.

Unfortunately, LR 13 Export ignores setting Preferences > Performance > Use Graphics Processor to Off -- it uses the GPU regardless of the setting. The only way to test whether the graphics driver is causing the problem is by booting Windows into Safe Mode With Networking. But simply seeing System Info will be an easy first step.

That's why I suggested testing post processing and not exporting since the OP also experiences crashes and very strange behavior (flickering, dark screens, freezing) just in post. Just realized that another cause of this might be a failing system hard drive/SSD.

Ok last thing now I've checked:

I import my photo's in LRC directly from my SD card onto my PHOTO folder on my NAS.

I post process the photo's and export them into a subfolder JPEGS in the same location on the NAS.

I've now copied a specific folder with my RAW files to my C: drive, updated the folder in LRC, and started exporting to the subfolder JPEGS in the same location on the C: drive.

All pictures exported well without freezing or whatsoever.

I find this strange, because I have a 1GB connection full duplex to my NAS and copying around 80MB/s. Ideal world this would be 100MB/s, but.. When I check the connection from my PC to my NAS via PING, I have an avarage roundtrip of 0ms (so basically <1ms).

I think the bottleneck here is the NAS but WHY?

I don't want to change my workflow. That is why I have a NAS. I don't want to copy to my C: and then have to copy all over to the NAS.

Anybody else using the same method as me, directly going to the nas for import without an issue?

And another update:

I was too soon with celebrating. Also now, during post processing, LRC crashed. A lot of errors and screen flicker, dark, ...

So the move of the folder to a C: drive was not the fix.

"It make sense it would be the GPU considering the screen flicker etc.. but in all other applications, Photoshop included, I cannot replicate these issues."

LR uses the graphics processor much differently than other apps and has been tripping over driver bugs in parts of the drivers that apparently aren't well-tested by the manufacturers.

" with the export... it freezes."

Unfortunately, a LR 13 preferences bug prevents you from disabling the use of the GPU for export. So do the step 3 (Safe Mode With Network) test above to verify the export problems are indeed triggered by the use of the GPU. Hopefully the preferences bug will be fixed in LR 13.1, due in a couple week.

"So it did export some pics, but a lot it skipped"

LR exports photos concurrently and out-of-order, taking advantage of the multiple CPUs. So if it crashes in the middle, you'll see just those photos that completed.

So, I restarted in safe mode with networking.

I got there the annoying message: ctfmon.exe: System detected an overrun of a stack-based buffer....

Searched what this error could mean and solutions.

Did SFC/DISM and other stuff, including a CLEAN BOOT. Error was still there but.. I booted now into W11, normal but with clean boot.

Without any post processing, I did the export and all photo's were exported.

I'll try tomorrow to do some post processing and export afterwards.
