Lightroom 7.3.1: Often not updating rendering in full res in develop module

It happens very often (but not always) in develop module: Image quality is not updated correctly (full res rendering) when modifying settings. You see banding color artifacts of low res rendering. It usually can be fixed during zooming in 1:1 temporarily.  This is a little annoying as you need to do this quite often. This effect appears usually after having done multiple editing and switching between different viewing modes (e.g., compare or grid view and back to loupe mode).

Same here on Windows 10.

Do you have "prefer smart previews for editing" checked in Preferences > Performance, by any chance?

yes, indeed it is in certain situations. please see my post further below....

Yes, I see this too sometimes. It seems that Lightroom does not always re-render the library preview at full resolution, so you have to zoom in 1:1 to force it. I don't use 'prefer smart previews for editing', so that does not seem to be the reason.

indeed - I checked with and without 'use smart previews instead of Originals for editing' on Mac version - both ways the issue is often there. Actually it seems to be never rendered in full res until the image is zoomed into once.

I just noticed something that could be related to this issue : when hovering the presets, I observed that some of them had absolutely no effect. Very strange. Until I understood that if the settings modified by the preset are located in a development panel that is disabled (switch button set to Off), the live preview doesn't take these settings into account.

This is questionable. The live preview should show the full effect of the preset by temporarily re-enabling the setting panels that are switched off. Otherwise, this doesn't make much sense.

@Patrick Philippot - that is an interesting observation. I will ask the team for a ruling on expected behavior.

This issue is really happening very very often and annoys me. I noticed that in develop module in reference mode the not updated full res rendering is showing in both images, but only in the active image zooming in/out resolves that issue for the current image. It does not help in the reference image - never a full res image after zooming in/out again. The image is full of artifacts which does not really allow to compare image quality. It happens with and without having GPU rendering enabled. As it is so easy to reproduce at least on my machine, is there any news or feedback that this behaviour can be reproduced?

Another interesting observation - maybe it can help to pin down the root cause:

In "library/compare" mode:
  - the images are shown in low res/low quality until you zoom in/out (or maybe if you have already by some other means forced LR to compute full res image)
  - both in "select" and "candidate" image views this happens, in both views full res can be forced by zooming in/out again
  - it does not depend on GPU activation
  - it does not depend on preference setting: "develop - use smart previews instead of originals"

in "develop/reference" view:
  - the images are shown in low res/low quality until you zoom in/out (or maybe if you have already by some other means forced LR to compute full res image)
  - both in "reference" and "active" image views this happens, but only in "active" view full res can be forced by zooming in/out again, it does not help in "reference" view
  - it does not depend on GPU activation
  - it does not depend on preference setting: "develop - use smart previews instead of originals" - if unchecked, after a delay of a second full res image is rendered

So, Victoria is right in certain situations. It seems that smart preview use is not properly implemented/tested on all the many different combinations of views/modules. It was not an issue in earlier versions, however. So I really would appreciate if this could be fixed - it is really slowing down processing workflow for me.

another place where the images don't get rendered in full quality:
slideshow - neither preview nor in the play mode full screen :(

both in library mode and in dedicated slideshow module.

I've just updated to 7.4 and the issue is still there. I make a change in Develop and then go back to library and image is all blocky and low res until I zoom 1:1. very annoying and a waste of time

I'm ALSO running 7.4 and I'm encountering a SIMILAR problem (possibly the same one, though what I'm seeing is NOT corrected by viewing at 1:1). 

On 7/11 I put an entry in the community forum showing screen shots of two images and how they were changed by viewing at 1:1.  Initially I believed previews were being rendered correctly once the images had been viewed 1:1 (this MAY have been prior to upgrading from 7.3.1 to 7.4, but I do not KNOW this).  I've since concluded this is not always true, certainly in 7.4.

Nikon D850.  Using Focus shift to create series of images with enhanced depth of field.  For example, using a 12-image stack:

Process the first 7 images in an external program and send the result back to Lightroom.

Process all 12 images and send that result back to Lightroom.

The thumbnails and loupe images look IDENTICAL, which they are not.

Open the 7-shot image at 1:1.  Do the same thing with the 12-shot image.  They STILL look identical.  After loading and viewing at 1:1 they continue to look identical at 1:1 and in loupe view.

I deleted the images from the disk and recreated them, then examined them again at 1:1.  The results are the same.  The previews in Lightroom show no perceptible difference whether in loupe view or 1:1.

I have verified that the images ARE IN FACT DIFFERENT by viewing them in Bridge.  At 1:1, in Bridge, the images are definitely and distinctly different.

I ALSO checked in Photoshop, and the images are fine there - all distinctly different.

This has happened repeatedly. I do not use smart previews.  I do not use Embedded & Sidecar, though I have TRIED that and gotten the same result.

Meanwhile the problem is back and worse than before in LR Classic 7.5
in both Library and Develop modules by default no high quality rendering is taken place in fit to window mode. In Dev Mode one has to zoom in to max and back again to achieve full res rendering, in Library mode it never renders in full quality. This is very annoying - no matter whether GPU is used, smart previews are applied.

Anyone found a solution for this? I edit a lot of photos and this issue makes me waste so much time.

stef, 

You likely need to do a clean reinstall to clear the issue.

1. Close Lightroom.
2. Restart your computer
3. Uninstall Lightroom via the Creative Cloud app
4. Restart your computer
5. Reinstall Lightroom from the Creative Cloud app
6. Restart your computer
7. Launch Lightroom and wait 5 minutes. 

Do you still see the issue?

Thanks, Rick - it helped partially. In develop model the issue is gone now. Still, in Library mode the issue is available, update to high quality rendering without lots of artefacts only after manual zooming in/out.

You might try rebuilding your Library Previews to speed up the rendering.

well, to wait a second or two is kind of acceptable, but to be forced to manually zoom in and out again to get LR to render image correctly is annoying. At least I am back to the state that the problem appears in Library and Slideshow mode, not anymore in Develop mode. Still very annoying and slideshow completely useless meanwhile.

I confirm that for me the reinstallation solved the issue in Develop module but it's still present in Library module, and it's not a matter of waiting. You MUST zoom 1:1 to get rid of the blocky and color artifact. very annoying.
