Question

Main image View hangs up to 10s when switching photos in develop, rest of the UI stays responsive.

I'm having issues with the speed of the develop module. It completely disrupts my workflow and significantly slows down my pace. When I'm finished selecting my images and I quickly want to adjust my images in the develop view, most images display instantly as expected. But sometimes the all of the UI changes, except the main image view. I can even do adjustments in the dev panel (I use a streamdeck via plugin to do this) and the commands arrive in the develop pane, but the image in the main view is still the old image, and it does not update. This can take up to 10s.

All this is happening on a Macbook Pro M4 Max with 64GB RAM und 2TB SSD. The images are RAWs from a Sony Alpha 1. From a pure technical point of view, there is really no reason why it could take this long to load 55MB of RAW data from SSD into any kind of other Memory on this type of hardware.

I would love to find out which piece of software is blocking the main image from displaying for such an incredibly long time. I am also unable to reproduce the problem. I thought deleting the previews from the catalog entirely via finder would give some remedy, but actually it's not. It is a problem that is occurring *every* single time I edit a job, but I cannot reliably perform a routine that would trigger the problem to occur. It's a completly random thing to happen every 1-10 photos, but only while editing images. If I just scroll through the images in develop, it seems it does not happen. But If I do copy and paste commands and adjust a few sliders it happens routinely and it's honestly driving me crazy.

Anyone else experiencing this kind of behaviour in the recent versions? I feel like it hasn't been this severe in the past.

Are you saving XMP files? If so try pausing that whilst you're editing (click on the identity plate top left and it's in the drop down menu).

I indeed save XMP files. Is there a known issue with this? I'm having trouble aligning saving a 4kb xml file with freezes rendering a develop view, but indeed I remember LR occasionally bragging about still being busy writing xml files, which always made me wonder how such a simple task could possibly take so long on modern hardware ...

I'll give that a try once I manage to rule out the plugin.

@Wolfgang Lienbacher , you need to be aware the Default option of LrC is not to write XMP to the file, when you are working with LrC the application is reading and writing to the Catalog file. LrC can function without XMP files.

When you import images into LrC and there is XMP data available the data will be reading, LrC does not "Automatically Read info from XMP files, this requires a manual input from the user.

There is an Option in the Catalog settings to Automatically Write Metadata to XMP, however this is not a primary function so info is first written to the Catalog. The XMP data is necessary to share info to Bridge/ Camera Raw of other applications.

When you have the option selected performance will be affected particularly if you are using edits using AI functions like Denoise etc.

You can pause the Auto Write to XMP when carrying out these functions and unpause it again when you have finished your editing.

What software are you using? What version NUMBER? (We need the version NUMBER and not words like "latest" or "up-to-date") What version NUMBER of MacOS?

Mac OS 26.1 and LR 15.0.

It has however not been specific to these versions, it's been happening in the past few versions as well, I only had the romantic idea that issues like these would resolve themselves at some point in thime, but I've come to the conclusion that this is indeed just a romatic idea.

@Wolfgang Lienbacher , you stated in your original post " I can even do adjustments in the dev panel (I use a streamdeck via plugin to do this) and the commands arrive in the develop pane, but the image in the main view is still the old image, and it does not update. This can take up to 10s."

There have been significant changes to LrC in the past two years, have been getting updates from the developers of the Plug-in you are using.
