P: Image Degradation when zoom in Library module

[davidc37375278]

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.

Confirmed here also. Sigh.

(iMac 27" 5k, Catalina)

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.

[davidc37375278]

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

Macbook 12" 2016. Same problem. (On all zoom % from 200% to 1600%)

[alexskunz]

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.

@Rikk same Problem here after update  to Version 10, on a 27“ 5K  iMac, MacOS 10.15.7

[FeedbackCommunityMember]

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

[FeedbackCommunityMember]

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.

[Bob Somrak]

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.  

[FeedbackCommunityMember]

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)

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

[Pavan Kumar T S]

Hi, thanks for reporting! The issue could be replicated and have logged a bug for it. 

[Bob Somrak]

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

[herrmmku]

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. 

LR Classic 10.0

Mac OS 10.15.7

@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. 

[Jerry Syder]

This is the link - the fix would be announced here.

[Joram98A1]

Same with me, already at 100% zoom though. 

LR Classic 10.0

@Rikk 

Same problem in 200%, iMac 27'' (late 2014), macOS 10.15.7, LR 10.0.

[FeedbackCommunityMember]

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

*tlangnickel This worked for me, too. Thanks for posting this!
