Lightroom Classic: Images not sharp unless I zoom in and out

if I go from one image to the next in the library or development module they often are not sharp unless I zoom in and out. It does not happen with every image but with a lot of them.

Funny enough the problem does not occur if I scroll through my images on LR 4 so it definitely has to do with the Classic CC version.

I am using MAC OS High Sierra version 10.13.4
Please help

Did you have "Use Smart Previews instead of Originals for image editing" checked in the Lightroom preference dialog? Uncheck it if you always prefer Lightroom to load and edit the originals.

Make the standard Previews big enough for your Monitor.

This is a known bug and has been reported to Adobe, but it has not been dealt with yet. Indeed super annoying. What works is to zoom in to 1:1 and then zoom out again.

Ok. What is the version of LrClassic that you are running?

Do you see any render difference by toggling the details panel on or off? When Lr renders the image at less than full resolution (1:1), the rendering of the Details panel settings including sharpening would be an approximation. Can you share a copy of such photos plus the settings online?

I've installed new version from scratch (deleting the old one entirely, keeping the prefs only) and it seems to work now.

Good news for you and all others who use Windows. However, this “workaround” does not work for those who are using MacOS.

If it helps, I also changed Standard preview size from 1920 (my monitors' width) to 1680px, as I never view previews on the entire screen.
Preview Quality from Med to High

Also unchecked "Use Smart Previews..." in Preferences/Performance.

i have found a few scenarios where (for me, 2nd monitor) the photo does not fully render unless you do something to it. the 2nd monitor will show a less than sharp photo, so i do a quick + then - (brightness up and down) and then it snaps into place. I have found other cases when doing autosync on multiple photos that only the first photo gets adjusted but the others don;t unless "touched" (for example, running a cursor over them in the filmstrip at the bottom of the screen).

Could be related to what I reported on a few months ago:

This reply was created from a merged topic originally titled LR Classic - not able to see the sharpness unless zoomed.

I use Canon 5dmk4 and when I load RAWs, most of them come "soft". Those made with shallow depth of field. If I use big apertures, like f1.8, I need to zoom in, wait for it to completely load (slow) and only then when I zoom out to fit my screen I will have perfectly sharp image.


So steps to produce this:

1. Load any shallow DOF image
2. Normal screen size, relative to the monitor is not sharp. It looks kind of soft with difficult to predict where the focal point is.
3. Zooming to 100% renders the image entirely and nicely. But it's a very slow process.
4. Zooming out and having full image on the screen is finally tack sharp.

Any ideas?
It wasn't like that before. I remember LR rendering any screen size nicely and sharply even before going to 100%. So either they changed the rendering, some settings or it's a bug.

This reply was created from a merged topic originally titled Lightroom Classic CC: shows low resolution image after changing settings.

The issue happens very often but not always. Lightroom shows low resolution image after changing settings (see the screenshots). If I change current image twice or even click on the same image on the ribbon, then it shows the correct image. The issue is so annoying that I'm going to stop using Lightroom just because of it. Please fix it as soon as possible!

Low resolution image:

Hi there, I think this issue is the same: https://feedback.photoshop.com/photos...


There’s a workaround (re-install lightroom, reset settings, discard previews and rebuild previews) but it only works in Windows.


I’ve recently purchased a MacBook Pro and have been struggling with this since. The previews used in the library look very low quality. Especially on darker images and shadow areas. Zooming in at 1:1 or more does render a full quality preview in develop but not in library nor on slideshows.


I can see that this thread as been marked as “in progress” but does this mean that the issue has been identified and a fix is on the way? Any idea of when this will be out?

This problem also happens when using the full screen display option (F key) and zooming in and out in the full screen image. Sometimes, after zooming out, the full screen image is displayed in low resolution.

Yes, I'm using an adequate size for the standard previews.
