Bug Reports

On macOS27, LR Classic is hanging when I try to delete a photo from my library. Happens with either a single, a few, or a lot of photos. Hit “delete” and the UI hangs. Exports currently underway keep running but the UI is unresponsive. Force quit required. Happened on Classic 15, didn’t report since I assumed it was a macOS27 compatibility thing, but it’s still happening exactly the same on Classic 16.Sometimes the delete works, but most of the time it doesn’t. Getting pretty annoying now.

I just updated both Lightroom Classic and Photoshop today. I selected two images in Lightroom Classic. I went to edit them as a stacked layer in photoshop. Instead I get this error message in photoshop, "load layers need at least two files selected.” Device name    OriginLaptopProcessor    11th Gen Intel(R) Core(TM) i7-11700K @ 3.60GHz (3.60 GHz)Installed RAM    64.0 GB (63.9 GB usable)Graphics card    NVIDIA GeForce RTX 3060 Laptop GPU (6 GB)Storage    852 GB of 2.73 TB usedDevice ID    66FE5495-1690-41A9-A517-02EF8DBEBC18Product ID    00330-80000-00000-AA768System type    64-bit operating system, x64-based processorPen and touch    Pen supportEdition    Windows 11 ProVersion    25H2Installed on    ‎7/‎21/‎2025OS build    26200.9974Experience    Windows Feature Experience Pack 1000.26100.385.0

I often find that Lightroom Classic sync to the Adobe Cloud gets stuck uploading images.Removing the offending images and from sync and all synced images usually clears the issue, however I can repeat the issue.Add some previously un-synced images (mine are usually new imports)  to a collection and let them sync - wait for the icon to stop spinning and turn green. Remove some of the images from the collection Then immediately add some of those removed back into the collectionThe added images just added back in to the collection just sit in an 'uploading' state. I have left them trying for hours.I have observed on occasion that LrC will remove the newly added images from the local collectionI occasionally make a mistake and change my mind about images I've removed from collections so add them back.I have done the above steps several times now and find the results consistent.

When I go to set margins in the print module, it won’t let me set a margin less than .88”. ＊Moved from Lr to LRC by a moderator.

I updated to LrC 15.5 a few hours ago.  Since then LrC has problems with video files.  The first problem I noticed was that when I tried to synchronize a folder that had two new video files.  After a couple of minutes I got the error message “An unknown error occurred while reading the video file. (2)”.  I had just completed those files with DaVinci Resolve so I went back and produced the same files again to check if DR had made an error.  When I tried again with the new files but got the same errors.  I was able to play both videos without any issue using VLC Media Player, so they seem to be OK.  I then shutdown LrC and did a backup including optimizing the catalog, and then restarted it to see if that made any difference, but same error.  Then I started looking at other videos that were already in LrC and found that when browsing them in the Library module, most of them pop up a message “There was an error working with the video”.  They will not play in LrC but work fine with VLC Med

History panel Clear All button leaves the last history entry – Lightroom Classic 16.0 (Windows)Description of issue:Since updating to Lightroom Classic 16.0, clicking the X (Clear All) button in the Develop module's History panel no longer clears the entire history.All history entries are removed except for the most recent entry, which remains visible.In previous versions, clicking Clear All would completely empty the History panel.Steps to reproduce:Open Lightroom Classic 16.0 on Windows. Select any photograph and enter the Develop module. Make several Develop adjustments so that multiple History entries are created. Click the X button in the History panel to clear the history. Observe that the last History entry remains.Expected result:The Clear All button should remove every History entry, leaving the History panel completely empty, without changing the current Develop adjustments.Actual result:All entries are removed except the most recent History entry.Environment:Application: Ado

It’s really a shame. Over the months, I tried various tips found online, but without success. Today I installed version 16.0, hoping that I could finally import my iPhone h.265 videos again. Unfortunately, no luck. After months, I have now given up and reinstalled 15.4.1. And boom, everything is working again.Windows 11 Pro 25H2The import error started with Lr Classic 15.5.

When using the filter  on file type the Digital Negative / Lossless selection is returning the incorrect number of images. The numbers in the filter bar is correct but not returning all images that are Digital Negative / LosslessThis happens throughout my catalogue, everything is in sync and used to work correctly. My DNG files are created by various different software and the number in the filter is correct but images are always shown less.On investigation the images not shown were created with older version of Lightroom by importing as DNG around 2010 to 2012

Lightroom Classic closes on its own (crash to desktop).2. Lightroom Classic freezes and must be terminated from Task Manager.3. The whole system hangs.4.

Since updating to Lightroom Classic 16.0, I have noticed a brief ripple-like blur or screen refresh affecting the photograph immediately after releasing the mouse on the first AI Remove selection.The distortion lasts only a fraction of a second and does not affect Lightroom's interface or panels.System: Mac Studio M1 Max, 64 GB RAM, Apple Studio Display and LG 4K secondary display.Steps to reproduce: Open an image in the Develop module. Select the Remove tool. Paint a selection and release the mouse. A brief ripple-like blur occurs across the photograph. Additional selections work normally without the distortion. Leave the Remove tool, return to it, and make another selection. The distortion occurs again on the first selection. GPU testing: Auto: Distortion occurs. Custom: Distortion occurs. Off: Distortion disappears. Expected result: The image preview should remain stable when applying the first removal.Actual result: A brief image distortion occurs when GPU acceleratio

Cannot utilize mask presets in Lightroom Classic after update to version 15.6. After waiting over an hour for the AI models to “download”, nothing happens and starts all over again when another masking preset is used. I have logged out, logged in, run as administrator, uninstalled. re-installed Lightroom Classic. Nothing works.  

Since updating to Lightroom Classic 16.0, Develop presets that include a profile (Treatment & Profile checked) intermittently fail to apply their profile. The issue did not occur in 15.x.Steps to reproduceRestart the computer. Launch Lightroom Classic 16.0 and open a raw photo in Develop. Apply a Develop preset that includes a custom profile (XMP creative profile or DCP camera profile).Expected resultThe preset applies its profile.Actual resultNothing happens. The Profile field stays unchanged and the profile is not applied. Re-clicking the preset or waiting does not help.The referenced profile is installed correctly: it is listed in the Profile Browser and can be applied manually from there without any problem. Only the preset fails to apply it.WorkaroundQuit and relaunch Lightroom Classic. After the relaunch, the same preset applies its profile correctly, even immediately after launch. The issue returns after the next computer restart.PlatformsReproduced on macOS and confirmed by

Adobe Lightroom Classic 16.0 (November 2026) gestern aktualisiert auf 2 MacBooks Pro unter macOS 27 Golden Gate.Auf beiden Laptops ist im Menu „Apfel P“ ausgegraut. Auch werden markierte Fotos nicht im Druck-Modul angenommen. Ein Druck ist auf verschiedenen angebundenen Druckern aus Lightroom Classic 16.0 nicht möglich.Andere Programme drucken fehlerfrei.

Version / OS: Lightroom Classic 16.0, Windows 11Description: When a DNG/TIF containing Google Photo Sphere (XMP-GPano) metadata is exported as a smaller JPG, the GPano pixel-size tags are copied across unchanged. The exported file’s real dimensions no longer match them, so it is an invalid 360 file for strict readers. Facebook for example no longer sees it as a valid 360 file.Steps to reproduce:Import a full equirectangular 2:1 DNG with GPano tags (mine: 18250×9125, stitched in PanoVolo 1.13.0). Export as JPG, resized to 8000×4000 (metadata set to “All Metadata”). Read the JPG with ExifTool.Expected: FullPanoWidthPixels, FullPanoHeightPixels, CroppedAreaImageWidthPixels and CroppedAreaImageHeightPixels are updated to 8000 and 4000 to match the file.Actual: All four still say 18250 and 9125. The file is 8000×4000, and the tags describe a sphere 2.3 times larger than the image.Impact: Panorama readers that check these values can reject the file or read it as a partial panorama, and I hav

This is reported as a follow-up to That bug was resolved in 15.5, but it is now back in slightly different form.

I figured it out.  There’s an opacity slider that I didn’t notice, and it was set to 74%.  I changed it to 100% and the remove works.  I never noticed that slider before.

After installing update 16.0 on a windows 11 platform the program will not close normally. Task manager / End task must be used to close Lightroom.

Description of issue:On macOS, every H.264 .MOV file fails to import ("There is a problem with the video file") or the import stalls, and H.264 videos already in the catalog will not play. The dynamiclinkmediaserver helper process spins at 100% CPU indefinitely, and a new stuck instance is left behind after each Lightroom launch. Simply opening the Import dialog on a folder containing an H.264 clip is enough to trigger it (thumbnail generation). HEVC versions of the same clips import normally.

The new Focus Point feature in LR 16 sometimes shows the wrong focus point in the Library Module but the correct one for the same image in the Develop Module.
