Lightroom Classic v10 buggy and library module makes sharp pictures fuzzy
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.
