Lightroom becomes unresponsive when scrolling/navigating thumbnails in any view.

GPU: GeForce GTX 1080TI

OS: Windows 10 Pro 10.0.19043

For many months now (it may be over a year at this point) I've had problems running the Windows application for lightroom CC. At one point it worked excellently, I was able to rapidly workthrough fresh imports, now it's impossible to get through any bulk amount of photos due to all the freezes.

When scrolling through photos in any of the thumbnail views (Square, Photo, or Filmstrip) the application becomes unresponsive for 30 seconds to a minute and one of my CPU cores will be at 100% for the duration. Basically any action that will require the application to display additional/different thumbnails results in a temporarily unresponsive application, this includes resizing the window itself in any multi-photo view.

I have no issues while actually editing photos, provided I don't accidentially navigate the filmstrip while doing so.

I've tried turning on/off the setting for storing a copy of smart previews, no difference.

I've tried many of the suggested troubleshooting related to performance issues for lightroom, but what adds to the frustration is many of these articles (by Adobe and elsewhere) are targeted to Lightroom Classic, not the cloud application, and many of the steps are not applicable or menu options do not exist.

I have tried using the application with GPU acceleration on and off, there is no difference.

The application works fine on my relatively lower powered laptop with no problems (other than lower performance which can be attributed to it being a less powerful machine)

I reinstalled windows, problem solved.

Sorta feels like a "screw it, nuke the problem" solution but the system was doing some other weird behaviour I couldn't explain and it had been a while.

sorting through and removing and rearranging photos in the lightroom classic library is an enormous part of my daily workflow. sorting tasks that used to take 15 minutes are now taking me hours due to this lightroom behavior. Im afraid im going to have to reinstall windows as you suggested. just wanted to check on if this was a permanent solution for you before I proceed.

Coming up on a year and I still have this issue. Just updated to latest version.

What performance monitoring have you done to find the potential bottleneck?

I see similar behavior on my backup laptop. However, I am 99% sure the problem is self inflicted in my case.

On my backup laptop, I have a 256GB SSD, with only 10GB available, and cache size in Lr set to the default.

I know the system struggles working in such a small space.

Note: I have 30K images and I believe 600GB of space used the cloud.

You might want to eliminate this variable.

There isn't any space constraints, that's been something I've been keeping an eye one.

I have noticed though that my cache is showing as having no size or 0kb, despite me allowing it to use space. It doesn't grow at all where as on my laptop it has a fair amount of size.

I don't know if this is expected behaviour as I have lightroom keeping full size images stored on another disk on the system.

My cache is also 0kb reported and basically when looking at the disk is also empty on my desktop where I have all originals on a secondary disk.

Based on your posted video above. I was watching disk 0; which is an HDD. This was jumping up to a couple percent at most. On my desktop where I have the originals on the secondary HDD (technically a mirror set) I am

seeing the HDD go as high as 60% when I scroll through the images.

I am making the assumption you have the SSD for drive C. And are using the two HDD for data storage. (Similar to my setup).

On the off chance this is a Windows/HW issue with the HDD (this test will NOT find all potential problem points). I would disable the local storage of originals (this will cause it to re-download everything when you re-enable). And just use the cache on drive C. And see how the system performs. Now if you have a lot of images, the drive C cache will only keep up with so much. But see if the performance is better. If yes, then you have an issue accessing the HDD.

I spent some time on this today, I tried following directions here to do an uninstall/reinstall, and clear preferences. Issues remained.

I've set my photo cache size to 0% and then up again in an attempt to clear the cache, Same Issues.

I tried scrolling/navigating while at 0% as well just to see if any change, still nothing.

While it was set at 0% attempting to navigate forward through my photos, LR would struggle while fetching thumbnails (increased disk/cpu activity while unresponsive).

While navigating back to photos it's already fetched there's no delay, LR flys through them no hangs. At one point though the entire grid view went blank, the program became unresponsive for 30-60 seconds and subsequently all the previews began appearing one at a time. Once the program became responsive again I returned the photo cache back to 25%.

I've then tried clearing/downloading the entire cache via manually deleting the folder in appdata, after starting the program again it was entirely empty as intended, it immediately went unresponsive, but clearly fetching cache data, for the entire period it was unresponsive the appdata folder was growing again to it's maximum size, and there was ongoing disk/network/cpu activity.

The cloud icon within the application indicated the sync was complete but disk/network/cpu activity remained, during this time LR was writing to the Proxies and Previews Folder, and less frequently the managed catalogue files in the appdata locaiton.

I left LR open until all system activity stopped.

Same issue remains, as soon as I start navigating through photos the program becomes unresponsive while fetching more thumbnails. While the program is unresponsive after scrolling I notice that disk activity is generally writing to the previews folder in appdata, once it's become responsive most of the activity is to the proxies folder.

The next time I have energy for this I'll try changing the proxies location per this post, just as an attempt to rule out any issues with the SSD appdata is on.

Ran out of patience for this today, added disk details to OP.

Both are here, I'm not entirely sure if the before version was captured during the problem as it's hard to get the preferences to open when lightroom is hung like that.

I have 8 albums.

Thanks, I will forward this information to the engineer. Leave the logs in place for a few days.
