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.

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 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.

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:

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

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.

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.
