P: Develop module loupe view is showing a double exposure with the previously edited photo.

As far as the visual similarity to the “using the arrow keys” issue, you can find the answer to that question by comparing the image(s) in that thread with the ones I posted here. It’s simply a superimposition of the previously edit photo with a reduced-opacity photo that I’m trying to edit. 

Hi Anshul, Thank you.
I use multiple displays, but in practice, 99% of the time I use only one for LR. As I mentioned, if I do open the image in the second display, it displays as intended (ie, without the double exposure).
Steps:
After editing dozens of images (no consistency here that I can tell), I go to edit a new image: open in Develop module, and the image displays with the most recent previously edited image overlaying an opacity-reduced intended image. The superimposed image is distorted (I assume cropping has to do with this)

Toggling GPU has no effect--the issue persists regardless.
I tried a new catalog with a few images, but since this problem usually takes many edits to appear, it’s not efficient to try and replicate the issue with a test catalog.
I’m afraid showing a screen recording from the point of opening the catalog sort of requires a crystal ball to predict when the issue will appear.

Hi ​@PhatsPhoto ​@jime40615875,

Thanks for reaching out and reporting this. Since this isn’t reproducible on our end and the behavior (ghost/double exposure in Develop but not Secondary Display) is quite specific, we’ll need a bit more detail to take this forward properly. Could you please help with the following:

• Share your full System Info

• Lightroom Classic > Help > System Info
• Click Copy and paste it here

• Confirm your exact setup

• Are you using multiple displays or just one?
• If multiple, does it always happen on the primary display only?

• Help us with reproducible steps

• Exact sequence (e.g., Edit photo A > go to Grid > open photo B > switch to Develop, etc.)
• Does it happen with specific images or randomly?

• Quick checks

• Does toggling GPU OFF (Preferences > Performance) change the behavior?
• Does it still happen in a new catalog with a few test images?

Also, please share a screen recording of your entire workflow, starting from launching Lightroom and showing the transition from Library to Develop when the issue occurs?

Once we have this, we can escalate it internally with clear repro steps.

Best regards,
Anshul Saini

I am currently experiencing this issue.  I can’t find any unusual settings that could be causing it, but there is one image that it is blending with everything else in particular.

I would really like to figure out if this is a glitch or a feature, as I can see a lot of potential if this is something that I do do with intention.

Greetings all, 

The team is having difficulty reproducing this issue. If anyone on this thread has precise, step-by-step instructions for reproducing this failure, please post them. 

Thanks!

Anybody else have this issue?

Have you tried resetting the LrC preferences?
