First edits get reset

[Joseph Allen-Keys]

This happens when I make an edit with a shortcut within the first second or so of navigating to an image in the develop module. It's cramping my workflow badly.

iMac M1, 16GB, library on SSD, OSX Tahoe 26.1, LR 15.0.1 (Been happening for a few versions now.)

Thanks!

Hi @Joseph Allen-Keys! Thank you for reaching out! I can understand it must be frustrating, especially when this has been happening for a while now. Is this issue occurring with all types of images or only with specific ones?

Here are a few things you can try to fix this:

1) Try purging the Camera Raw cache from LrC's preferences: In Preferences > Performance> Click on 'Purge cache' in Camera Raw cache settings, as shown in the attached screenshot.

2) Turn off the GPU: In Preferences > Performance > select 'Off' for Use Graphics Processor.

3) Try resetting your preferences: A corrupted preferences file can cause various issues.

- Try method 2 (The Manual method) from this HelpX article: How to reset Lightroom Classic preferences

Hope this helps!

Thanks for your reply @Noel Orridge - unfortunately, none of these have worked. I've tried the GPU preferences in all states, purged the cache and deleted the preferences, but the problem persists. I've also tried it on another machine. A MacBook Air with an M3 processor, and with a new library (having exported the project out of my main library.)

It seems to be a problem with the reading of the files (Sony A7iv RAW), as in the split second before the histogram is properly read, is when the edits I make will disappear. I had hoped a faster machine would help that, but it doesn't seem so.

I might be a rare instance in how quickly I make edits when I land on a new photograph. I can't seem to find any other users with this problem. Though it's also hard to search without getting results for how to manually reset all developments...

Thanks for sharing the update. I'll need more information about your workflow to help you.

Where do you keep the Lightroom Catalog and RAW files? Internal, or external drive? Please share more details, such as a video showcasing the error/behavior. 

Check if this helps:

Lightroom Classic > Catalog Settings > Metadata > Uncheck 'Automatically Write Changes Into XMP.'

Let me know how it goes. Thanks!
