Lightroom 2015.12: Folder synchronization doesn't work

I am running Lightroom 2015.12 on Windows 10. When I right click a folder and choose Synchronize Folder, it goes through the search to find new files, then opens the Import screen, highlights the folder I had selected, and a circle starts spinning just below the folder. After a second or two the circle freezes and so does Lightroom. I can still close the software, but it wants to check to see if there is a solution to the problem, which it doesn't find. If I go to the Import screen first and then select the folder I want to synchronize, everything works fine.

This problem has occurred in several previous releases of Lightroom, including the last two or three, but in the past, updates have corrected the problem. Lately, updates haven't been correcting it.

Any suggestions?

A Preference File will survive a Lightroom uninstall/reinstall. Sometimes weird behavior is corrected/cured by resetting the preferences.  That would be my bet here.  Try this:

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?

I just saw exactly the same thing on my Macintosh, with GPU unchecked. I can synchronize a folder if I do not check the option to show the import dialog, but if I do check that option I get the same problem.

Todd Shaner: I already have the Graphics Processor disabled. That is another issue I have that changes from one version of Lightroom to another. Currently, LR goes into a graphics frenzy from time to time when the GP is enabled. So, I'm currently having to leave it unchecked. The difference is that the latest version of Photoshop now no longer even recognizes my GP, so I have to uncheck it there also. If I check it anyway, PS will sometimes do crazy things and hang up. That's the first time that has happened with PS. I have the AMD Radeon 7800 series card. According to Adobe's list, it should be compatible, but I've also read that Adobe is having problems with some AMD cards, so not for sure.

I suggest checking your graphics driver version and update it if older than the latest 17.7.2 version here:

Make sure to restart your system after the update.

I keep my graphics card driver software up to date. I am already using 17.7.2.

It appears there are still issues with LR and the AMD graphics drivers:

https://www.lightroomforums.net/threads/lightroom-cc-2015-10-1-crashing-using-amd-radeon.31229/

This may or may not be causing your issue, but you can try the AMD Settings Utility change mentioned at the above post. Simon Chen is an Adobe Engineer.

From Simon Chen, chief techy at Adobe:

"Thank you Lance. I can confirm that this trick seems to work based on my testings with AMD Radeon Software Crimson ReLive Edition 17.4.4. As you suggested, launch the "AMD Settings” utility software installed as part of the driver software updates, click on Gaming, then Global Settings, then click on "Wait for Vertical Refresh" and set it to "Always on". Lr seems to work fine without crashing the AMD GPU driver.

If you later toggle the "Wait for Vertical Refresh" settings back and set it to "Always off", Lr also does NOT crash. The actual value of "Wait for Vertical Refresh” does not seems to matter, but the act of toggling the "Wait for Vertical Refresh” seems to change some driver factory default settings that would workaround the Lightroom crash."

Todd: Thanks for this info. I set "Wait for Vertical Refresh" to Always On  and so far LR is working without crashing. I also turned the GP back on in PS and it's working thus far. However, PS does not recognize what GP I have as you can see in the image below. LR recognizes it as AMD Radeon 7800 Series.

Try resetting you PS Preferences file ' On Quit' as shown below. Save a copy of the current Preferences file to the Desktop so you can easily restore it if the issue persists. Close PS and then reopen to reset the Preferences.

Okay, this is interesting. The main problem I had with PS when the GP was checked was when I tried to choose a photo in LR and tell it to Edit in PS. PS would open, but as the image tried to load, I'd get a message saying that PS had stopped working and asked if I wanted to close the program. Upon opening PS again, I'd get a message saying there was a problem with the GP and that it had been automatically disabled. With the GP unchecked, all worked well.

As you suggested I reset the Preferences file for PS. When I checked the Performance settings, it was now correctly displaying that it detected an AMD Radeon 7800 Series card and it was checked. I then attempted an edit in PS from LR and again the program stopped. Upon loading PS, I again was told the GP had been disabled. With it disabled, I attempted an Edit in PS from LR and all worked correctly.

Hmmmm.... What does this mean?

1) It means there's still some incompatibility with the graphics driver. Try resetting PS Preferences 'On Quit' again, but leave PS closed. Reboot after making these types of settings changes to make sure everything's in sync. Try again.

2) If that doesn't work try turning ON 'OpenGL Triple Buffering' in the Radeon app settings. Reboot, try again.

3) If that doesn't work set both Wait for 'Vertical Refresh' and 'OpenGL Triple Buffering' to OFF. Reboot, try again.

4) If that doesn't work go out, have a few drinks, and enjoy the weekend.

Well, I guess I'll be going out and having a few drinks, even though I don't drink. Maybe sodas? But hopefully I'll enjoy the weekend with the solar eclipse and all. 

In addition to what you suggested, I also tried setting the GP option from Advanced to Normal and to Basic. Those didn't work either. It seems the only way to get LR to successfully pass a file to PS is for the GP to be turned off.

New information. At the recommendation of a tech at AMD, I used a utility (DDU, Display Driver Uninstaller) in Safe Mode to completely uninstall the latest AMD driver. I rebooted and then reinstalled the latest AMD driver. I then reset PS prefs and tried editing a photo in PS from LR. Still crashed. I then set "Wait for Vertical Refresh" to Always On and turned on OpenGL Triple Buffering. I reset the PS prefs again and tried editing a photo from LR. IT WORKED! I don't know what all is going on here, but something seems to be afoot at the Circle AMD. Let's cross our fingers and hope it continues to work.

Good to hear–Thanks for the update! I saw one post where the OP used an AMD "Driver Cleanup Utility" and it corrupted his registry, so I hesitated making that suggestion. It sounds like you used a different AMD utility. Please post the download link to help others who land here and keep us posted. Cheers!

Here's the link to the DDU utility: http://www.wagnardsoft.com/forums/vie...

I would not have tried it had not it been an AMD employee in customer service recommending it. Be aware that at one point it says that it is removing known Registry Keys and will take a minute or two. It was much longer. In fact, I had decided to stop the program at 10 minutes if it never completed that task. At 9min59sec, it completed. Everything went smoothly. After reinstalling the AMD driver, I had to set up my default color profiles for the monitors and reboot. But all seems fine. But you never know when there might be some problems lurking in the corner.

DDU is a 3rd party graphics driver utility that seems popular in the Gaming community. Wagnardsoft's instructions suggest rebooting into Safe Mode when running it for best results. It's good to know this cleaning utility along with setting "Wait for Vertical Refresh" to Always On and 'OpenGL Triple Buffering' to ON resolved your issues. Please keep us posted with any changes. Great troubleshooting work Kathy!

Completely forgot that we went off-topic–Did this also resolve the 'Synchronize Folder' issue?

As I experienced the exact same issue on a Macintosh, I'd say that it didn't.

Johan is correct. It did not fix this problem. I tried turning off Scan for Metadata Updates, but that still didn't work. And if I haven't said it before, turning off the GP doesn't correct it either. I have heard that Adobe is working to speed up LR in the next version. There are a number of operations in LR that could definitely use speeding up. Scanning for new imports is one of them, especially when it comes to videos. Perhaps the Sync Folder problem will be solved as well...again!

The Synchronize Folder problem still exists in the new Lightroom Classic CC. I don't understand why this hasn't been fixed.

I can confirm that I am experiencing the identical Synchronize Folder issue as described by the original poster. I am running Lr CC Classic 7.1 on Windows 10. I have never had this issue in any previous release of Lr. However, I am using a new machine with the GPU turned on. My old machine never allowed the GPU to be enabled in Lr.

The synchronize folder issue seems to have been resolved with the latest release, but time will tell. Sometimes the problem comes and goes.
