Problem rendering in Develop module when scrolling photo full screen

[JBoisve]

Hi

I have a problem when scrolling photos in develop module in full screen.

When I scroll photos and stop to one particular photo then the rendering never completes, the photo remains blur. I tried bot with Graphic Acceleration set to ON and also set to OFF.

I do not notice this problem in Library module, only in developp module.  The only way to see the picture completely rendered is to press next button and then back button and then the picture is well displayed.

thanks

Jules

Which version of Lightroom Classic?

Which version of Windows?

Have you tried restarting your computer?

[AxelMatt]

Does this happens only with one image and always the same?

If yes, try to create a 1:1 Preview manually. Or delete the image from the catalog and reimport it again.

Another try is to reset the preferences of Lightroom Classic:  How to reset Lightroom Classic preferences (adobe.com) 

It's recommended to backup your preferences before you reset the preferences to the default settings:

If this doesn't help provide a copy of your 'System Info'. This can be get from the LrC Help > System Info menu item. There's a copy button in the System Info dialog. Press this button and paste the info into your next forum post.

Hi,

I have Windows 11, Lightroom 14.0.1.

It doesn't happen with one image. in particular.

Yes, I try to restart my computer.

I tried also with my Laptop (windows 10, lightroom 14.0.1) and I have the same problem.

See system info in attachment

Thanks

Hi

I tried delete all the preview.  When preview are deleted then If I scroll then the word 'Loading' appear and stay like this forevever until I press a key like 'next' or 'back' .

[AxelMatt]

Do you have reset the prefrences?

Try to change the GPU Setting from Auto to Custom.

Going to the Preferences > Performance > Camera Raw Cache Settings and try to purge the Camera Raw cache.

Try to create a new catalog and import several images and check.

Hi

I tried both GPU On and OFF. Same problem

I tried with a new catalog. Same problem

I didn't try to reset Preferences because I dont'want to loose them.

Thanks

As I wrote in my former post it's recommended to save the preferences before do a reset. So you can restore the preferences in case that the reset doesn't help.

See here: Preference file and other file locations | Lightroom Classic

Preferences  

• Lightroom Classic: C:\Users\[user name]\AppData\Roaming\Adobe\Lightroom\Preferences\Lightroom Classic CC 7 Preferences.agprefs

To reset your preferences in Windows, restart Lightroom Classic and immediately press the Shift + Alt keys. In the resulting Reset Preferences dialog box, indicate you want to reset your preferences.

Copy the .agprefs files to a save aera of your hard disk before resetting the preferences.

Can you post in a reply a screenshot of your LrC /Preferences/Performance/

For Camera RAW CACHE Settings, 10 GB

Ok, I was half way expecting 5 GB. Adobe states that the default value of 5 GB is too small, to try at least 20 GB.

So you do have more than the default, but just 10 GB. Perhaps bump that up to 20 GB or more.

The Camera RAW CACHE limit will effect Develop Module edits. it will not effect Library module edits. It is where the Develop Module previews are created, so too small, poor performance. The larger the LrC session you have in terms of photos being edited, the larger this needs to be. Most people find they need to experiment with this as their are no fast and hard rules on it (how much is enough??)

P.S. the Camera RAW CACHE does not need to be in the default location. It can be on any hard drive, any folder. It does not need to be in the same location as the catalog or the photos.  Now the Camera RAW CACHE can take advantage of being on your fastest hard drive (as so does the catalog as well, but not the photos). You might see performance improvements if you take advantage of that. And on a Windows PC, some state to try to avoid placing it on the C drive where your Windows paging file is located due to the two completing with read/wrights, but that is a very small performance hit, and may not be worth the trouble.

[JBoisve]

The camera raw cache is on my fastest drive (NVMe) and currently the folder is using 985Mb very far from 10Gb.

This is a behvaior I notice since the latest updates v14 but it does not means it was not there before.

Thanks

Also to mention the problem is only in Developp Module and Full Screen Preview  (when pressing the letter F) otherwise when I scroll and stop to a photo then the Rendering is done completely.

Thanks

I reset Preference and same problem

I just see this file in appdata/roaming/adobe/lightroom :  lrc_console.log which contains this:

Lightroom Console Tue Oct 29 10:01:14 2024

L: maybeAssignLayoutAttributeL had an unhandled key: margin_right

render FAILED!!!!

[donnab15030387]

I too am having the same issue, except I don't get the render FAILED message in my log.  I just get a lot of "file not found"  It never comes up with the crash reporter, so I have no way to auto send the 30 or so crashes I've had in the last 4 hours.
