Stitched Panorama unsharp in Develop module, but displays pin sharp in library module

[Davidwa]

Lightroom 10 - When I use photo merge Panorama to stitch together 3 or 4 images into a panorama the resulting panorama appears unsharp in the Develop module even when I enter full screen mode. If I switch to Library module the same panorama displays pin sharp.  Why do panoramas have an unsharp out of focus appearance only in the Develop module.

First troubleshooting steps:

1. In Develop, zoom in and then out on the image -- does it then get sharp?

2. Try setting Preferences > Performance > Use Graphics Process to off and restarting LR. Does the image get sharp?

1)  yes,  when in Develop module if I zoom in it takes about 1 1/2 seconds to sharpen and stays sharp when I zoom out.

2)  It makes no difference if I switch on or off use graphics processor,  it still will only sharpen of I zoom in and out, Takes about 1 1/2 seconds regardless if the graphic processor on n or off.

So why should I have to zoom in and then out to get it sharp, I dont have to do this in the library module.

Thanks

Similar behavior has appeared infrequently over the years in Develop and in Library -- clearly undesirable. You could try doing Preferences > Performance Camera Raw Cache Settings > Purge Cache. 

If that doesn't help, I suggest you post a bug report in the official Adobe feedback forum, where Adobe wants all bug reports and feature suggestions: 
https://www.lightroomqueen.com/send-bug-report-feature-request-adobe/

Be sure to include the first ten lines of the menu command Help > System Info.  Provide all the details, rather than linking back to this thread -- experience shows that Adobe developers tend not to follow the links.
