For some reason, smaller photos enlarged to fit screen in LIBRARY module stay pixelated and are not enhanced as they were in all previous versions of LR. Actually they do, but for a second and then switch to the lower resolution. Enhancement works fine in EDIT module. How to fix this please? - Thanks!

I found a workaround that fixes the issue and I wanted to share it. My computer is a 5K iMac. I had (but was not using) a small program called QuickRes that allows for a wide variety of screen resolutions. Apparently, Apple uses a technique called HiDPI (high dots per inch?) that normalizes the high res screen to adjust objects and texts to a usable size. The HiRes program allows the same resolutions both with and without HiDPI. Use it to go to the same resulution your screen was set for but wit...

Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Past that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut as that is just so much dead space to us non-Techs.

Yes, jpegs. I've used LR since the original Beta and never had this problem. Is this my system info as you asked for? You really want all this in a message? Thanks.

I have the same issue and had to revert the update. It looks like (on a 5k iMac anyway) the 1:1 previews are not being handled correctly in LRc10. Full pixels are shown fine in Develop and Compare views, but Loupe and Full Screen show what looks like a zoomed version of the standard preview. Also if you try to delete and rebuild the 1:1 previews, the progress bar briefly appears when you select build 1:1 previews, then suspiciously completes almost immediately, no matter how many 21 MP files I select. When I reverted to the previous V9 version, all views were fine again, showing full resolution images. I tried blowing away the previews file and starting from scratch in V10, but that made no difference.

Same identical issue for me, reverting back to Lightroom 9, irritating being a beta tester by proxy

Well since I'm not alone, I will stop changing the settings, etc., since it is an Adobe issue apparently. Since 5K Macs are so common, I can't help but wonder how this could slide by them? I'll wait out a fix for a little while before reverting, however. I'm glad I have my old catalog... Thanks for replying.

I found a workaround that fixes the issue and I wanted to share it. My computer is a 5K iMac. I had (but was not using) a small program called QuickRes that allows for a wide variety of screen resolutions. Apparently, Apple uses a technique called HiDPI (high dots per inch?) that normalizes the high res screen to adjust objects and texts to a usable size.

 

The HiRes program allows the same resolutions both with and without HiDPI. Use it to go to the same resulution your screen was set for but without the HiDPI. The photo enhancement in Library will be fixed. So far, I have not run across problems with the HiDPI turned off.

 

It's possible that my very recent update of the OS to Catalina 10.15.7 might have altered the graphics accelerator somehow. In any event, it works for the time being. Thanks.

Sorry... but I just discovered that it does work but you lose the full pixel capability of a high res photo on the screen. In other words, a 3000 x 3000 photo will expand to twice the size of the screen because the screen itself is a lower resolution than the 5K max setting. Before, the LR frame looked the same but the image within the Library loupe would have the full 5K resolution capability that would easily accommodate a 3000 x 3000 photo. Now it doesn't.

 

So either Adobe or Apple needs to fix this using HiDPI. For what it's worth, LrC 9.4 worked as expected wven with the system update.

Hi, thanks for posting your attempts at a workaround. I had a further play with resetting caches and previews last night, all to no avail. It really looks like the preview generation and management is broken (at least for iMac users) in LrC10, and Adobe needs to address it. Like you, I've found 9.4 to work fine, so I'll be staying in that until it's fixed in the 10 release.
Thanks again.

ABELSEY, on the fear of beating this subject to death, I would be remiss is I didn't pass on that I just discovered that if you have an unenhanced image in Library, you can click on the SURVEY VIEW icon (N) above the film strip and you will see it enhanced (but with a thin white border). You can use the arrows to view all of the photos in your filmstrip that way. Saves me the trouble of reverting back to 9.4. - Andy

Hi Andy, thanks for the tip. I also found that if you are in the Loupe view, with the low-res standard preview showing at 100%, and you then go into Develop it will, of course, render the full resolution image. However, if you then return to Loupe view, it retains the full resolution image (no doubt just in memory), until you either then switch images or zoom back out, whereupon it unfortunately returns to the low-res standard preview.

 

I could probably live without Loupe view working for a while, but the killer for me is that Full Screen is also broken now. After spending all the time and effort to capture sharp, hi-res photos, having to look at them in a crippled fashion is just too much :-(.

 

Andy.
