Lightroom: UI slowdown listing publish service collections

In the Library module, whenever the list of collections in a Publish Service needs to be redrawn (scrolling it into view, or restoring a minimized lightroom), there is a massive slowdown lasting for a second or two, during which one CPU core is fully utilized.

I have the jf Flickr and jf PicasaWeb publish plugins installed, but the problem exists even in a fresh catalog with only a hard drive publish service set up. Upgrading to Lightroom 4.1 (from 4.0) did not help.

I have a tremendous number of publish services, and show/hide them all the time.

I wonder if this is one of the "filmstrip" issues? Do you have the filmstrip exposed? Try with it hidden.

Thanks, hiding the filmstrip doesn't appear to help though; I get the slowdown even with a new, empty catalog with all plugins disabled. Tried emptying caches etc. but no improvement.

Assuming there could be a problem with some remnant from a previous version (I've upgraded from previous Lightroom versions) in the application itself as opposed to the catalog, is there a way to reset all application settings? (preferably in a recoverable way, should anything go wrong)

Update: I appear to have found the crazy cause + workaround, but am unable to explain why it should have been a problem.

One of my monitors had two color profiles assigned to it, one from its driver and one from a calibration session (the driver profile was set as the default profile). By running Process Monitor and watching Lightroom I saw that it was accessing the registry and the *other* color profile, since it was somehow still registered as the system sRGB profile (in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ICM\RegisteredProfiles\sRGB).

Entering the system color management settings and deleting that calibration profile made the problem go away; showing/hiding publish collections is fast again. I have not checked to see if the problem is caused merely from having multiple color profiles assigned to a monitor, from having a non-default profile as the system sRGB profile, or if my files were somehow corrupted. Perhaps Adobe or someone else will be able to reproduce the issue by trying to replicate my circumstances. It seems weird that a particular feature (and nothing else) should be drastically affected by this.

I had exactly the same problem with publish services.
I run Process Monitor and saw that lightroom was trying to access some irrelevant profiles under HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ICM\RegisteredProfiles

I removed the irrelevant profiles from the registry and now Publish services run smoothly!

Thank you very much!

Wow, this worked for me too! I've been trying to cope with this problem for years to the point where the publish services weren't useful anymore. This bug has persisted at least since Lightroom 3. I removed all the other keys under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ICM\RegisteredProfiles except the default, and now the publish services are working perfectly again. Thanks a lot!

Thanks for the info. I, too, was having trouble with the publish services in Lightroom 5.2. There were a lot of keys in the RegisteredProfiles folder and I deleted all but the default. It runs fast now.

I was calibrating my monitor the other day using the Windows 7 color calibration steps. Not sure if that made my Lightroom ran slow.

Thanks!! This has really been bugging me for months.

I also had to remove the keys under

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Windows NT\CurrentVersion\ICM\RegisteredProfiles

as well as

HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\ICM\RegisteredProfiles

Hi,
I had the same issue with Lightroom CC 2015.12 on Windows 7.
This workaround still works!
I only kept the sRGB profile and removed th other ones.
