Lightroom Classic: Image Degradation when zoom in Library module

Increasing image size from 100% to 200% results in blurred image in Library module.

Move to Develop module and image sharpens up.

Return to Develop module and the image stays sharp until you move the cursor in to the image area, at which point it returns to a blurred image.

Same image(s) in Lightroom Classic 9.4 remain sharp at 1:1,2:1 and larger.

To clarify - These comments relate to the latest Lightroom Classic release 10 downloaded 21 Oct. 2020.

I am using Apple iMac - Retina 5k 27" 2017 with Catalina 10.15.7

I can duplicate this issue with Lr10 on a 2015 iMac 5k retina and macOS 10.15.7.  The image get pixelated with bad jaggies on the edges of sharp items.  I don't have 9.4 installed but don't remember it doing this.

Is everyone on this thread experiencing this issue using a 5K iMac 27 inch?  Or perhaps the better question: Is anyone experiencing this NOT on a 27 iMac 5k?

So far I cannot reproduce using a MBP and 5k External.

I also have a mid 2012 MBP running Catalina 10.15.7 which displays the same issue.

I also see these differences between Library and Develop at higher zoom levels.

Zooming in to 1600% (80s video game look!) and then switching back between Library and Develop shows some really fascinating behavior. The Library view uses the "refined" look of Develop rendering, but as soon as I move the mouse, it reverts to a blockier look.

Does anyone have a solution?  Rate and sort images is not possible in this displayed quality.

I have the same problem. Mac Pro 2013 and macbook Pro 2014. I have the original photos stored on an external HDD. When I disconnect the disk from the mac, the photos in the library and the develop module are of poor quality (high grain). After zooming in, the photo will not be found in better quality. It's unusable for my workflov.

I think this is a different issue.  When you disconnect the drive with the original photos then you are using "Smart Previews" so it is expected that the image quality is not as good.

you are right. But the quality is worse. when I use version 9.4, the photo in smart preview is better.

here are the photos:

Photos are exported from smart previews (the original photo was not used for export) one photo from version 10.0 and the other from 9.4)

10.0:

9.4:

I noticed that the photo is good in the library, but bad in the develop

It apparently is the same issue even when using smart previews.  I guess we will just have to wait for 10.1

@Pavan_kumar Is there a link to the bug so it can be tracked and we can follow when a fix will be delivered? I'm having the same problem as others. Thank you.

I also see the pixels in the develop module in 1600% view and in loupe view (e) they disappear. Also if moving the picture the loupe view remains better.

I have the same issue on MBP 16"( builded 1:1 preview ) images look degrade on zoom 100%. I cannot check my focus to any of them but the original images are fine when export and.

Recently starting seeing odd issues that others are reporting as well.  This was not an issue before the latest upgrade of LR. 

Photos look sharp in Loupe View and as soon as I move the mouse, it becomes blurry.  When I go to Develop, the photos are sharp again.

Today I updated my Mac with macOS Big Sur and the problem seems to be resolved.

Import RAW photos into LRC and zoom in to check focus/sharpness as part of culling process.  Alternatively go back into library module to look at images that have already been processed.  In the develop module, they are sharp if the photo is taken properly.  In the library module, however, the very same photos are blurry when zoomed in to 200%, this being the level of zoom required for LRC to show the pixel view at the same level as (for example) Olympus Workspace or Apple Preview show at 1:1 or 'actual size'.  There also seems to be a little bit of pixellation or jaggedness in places as part of the fuzziness.  Flip back to the develop module without doing anything and the picture is sharp again.  This fuzziness problem did not happen in previous versions and does not happen in Photoshop CC or Lightroom CC at the same zoom level.  It ONLY happens in Lightroom Classic V10.  Combined with other bugs, I found it so irritating and unusable that I rolled my LRC back to version 9.4.  Hey presto - everything works again and no fuzziness.  Before rolling back to 9.4, I tried my Mac with and without calibration and also tried it at various screen resolutions besides default.  The result was exactly the same.  The problem appears to be with LRC V10, not with 2020 iMac 5k or Mac Os Catalina.  Along with this, there is a problem with copy and paste of develop settings not working properly.  I will submit that separately in more detail.


Computer details for all of the above: 2020 iMac 5k running at default resolution.  Calibrated with xRite i1 Display Pro (and I tried the above with and without the calibration just in case).  3.8 GHz 8 core Intel Core i7 with 2TB SSD.  64GB 2667 MHz DDR4 RAM.  AMD Radeon Pro 5500 XT 8GB graphics card (tried on and off to check above problems).  MacOS Catalina 10.15.7.

On Windows and not observed consistently, it is sometimes slow to show an image with all edits applied upon returning to the Library module. While rare for a single image, sometimes it takes 1-4 seconds to fully sharpen and apply the rest of the changes.

 

When several images were edited before returning to the Library module, it does take a bit longer but this is not consistent.

 

Feel free to suggest a specific test for me to conduct.

BTW, the image always eventually views correctly and the issue seems less frequent since converting to 1:1 auto (4K) previews at maximum quality.
