Not sure this is a new bug or an issue with my catalogs or both, but after installing v13.5, LRC became very sluggish in several operations. Issues are not constant, they come and go every 5-10 minutes...I made a list:   After editing a picture, it takes several seconds to update metadata When I am in develop module, I can not longer navigate to next or previous image using left or right arrows. I have to switch no library module to do that or click with the mouse in the desired image. Flagging or scoring images takes sometimes several seconds to show. Scores sometimes revert to previous score, seconds after changing the score. Sometimes a photo already edited, its thumbnail appears unedited for several seconds in library, then updates to edited. Metadata filters in Library take long to show values or filtered pictures. In Library, selecting light out to dim or off, sometimes does not work until entering develop module. Almost all operations related to updating metadata are slow. Both LRC and LR keep syncing all day long, non stop since a week ago. LRC takes about 30 seconds to close   This is what I already tried to fix the issues, nothing worked. Stopped syncing to cloud. Stopped write to XMP. Purged cache (100GB maximum size). This helped for 15 minutes then issues returned. Optimized catalog. Tried all combinations of the GPU usage. Reset preferences. Uninstall/Reinstall both LRC and LR Mobile/Desktop. Deleted and recreated all XMP files. Rebuild sync data. Using another catalog. Removed plugins   My machine is a Mac Studio M1 Max running on MacOs Sonoma 14.6.1, everything updated to latest version, 64GB of RAM, all files on SSDs (catalog on internal SSD and RAWs/cache on 2 external Samsung T7 SSDs directly plugged via USB-C to machine. All SSDs having more than 50% free space). Apple Studio Display. Catalog has 35K pictures, 800 albums, including mostly Fujifilm RAWs, JPG, HEIC and some TIFFs. I have 4 installed plugins, LR Mogrify 2, JPEGmini, LensTagger EXIF Tool and WP/LR Sync. These plugins have been installed since years ago but issues started just since the introduction of version 13. Every new update makes things worse, not sure what else I can try. Any recommendations are welcome.   [Moved from ‘Bugs’ to ‘Discussions’ by moderator, according to forum rules. A ‘bug’ is not just another word for any problem with software!] ... View more

Since updating to 13.3, I am having several issues. First, almost half of the location data of my 40K catalog (country, city, state, etc.) has been either erased or changed to a variant like México/Mexico. GPS data was lost for 3K images. LR on the cloud has the same missing/wrong data. If I correct them in LR Classic, it reverts to the wrong one. Then it became very sluggish, especially when metadata reading/writing is involved like rating, library filtering, adding keywords, etc. When selecting Lights out mode, it does not work until I rate or edit a photo. Before this version it was instantaneous. Switching to develop mode takes about 3 seconds (it was less than 1 before) and advancing to next image takes 2-3 seconds as well, it does not matter if images are RAW or JPG. I already stopped syncing, optimize the catalog, increased cache to 99GB, deleted sync files, deleted previews, and generated them again, reset preferences, uninstalled, and installed again, removed presets, even tried a new catalog. Nothing seems to work. I noted as well that I have 1.5K stubborn images that I can’t save the metadata manually to disk. As soon as it “saves” it, it shows “The metadata for this photo has been changed in lightroom, save the changes to disk?”. I have paused Address Lookup, Face Detection and write to xmp. Generate Previews in Parallel is checked. Use of graphic processor is on Auto. I tried all other modes with no change in performance. All images are on a samsung T7 SSD attached on USB-C. The catalog and cache are on a mac studio’s internal SSD, M1 Max, 64 GB of ram, runing on sonoma 14.5. All updates for the OS and any app installed are up to date. Images are displayed on a Apple Studio Display. all drives have plenty of free space and there is enough RAM available, no swap. I note that for any action I do in LR Classic, like edit a photo or switching modules, etc… all cores go up to 90-100% (specially when generating previews) making my machine OS sluggish and all apps become unresponsive. Any suggestion to fix this behavior will be greatly appreciated. ... View more
