Blurry 1:1 previews on BigSur.

[Hysz]

Hello, I am working on newest Lightroom Classic, and this happens:

It's a fresh install, done yesterday, everything is up to date. I am using dual monitor setup with Eizo 24" Screen as a preview. As you can see on the left, everything is OK, picture is sharp and properly rendered, picture on the right however is blurry, even though it is 1:1 preview.

Thank you for any help regarding this problem.
