Lightroom 2015.3 not rendering properly in library

This is probably the third time I have posted on this topic in the last 5-8 years. Periodically I find that LR does not finish rendering some images in the library module. Normally the image will be rendered quickly and then as more computation is done the image will be rerendered with all the detail. Sometimes the final rerendering does not happen. If I switch to develop and then back to library then the image will be rendered properly.

THIS IS A SERIOUS PROBLEM. The reason this is serious is that a normal workflow is to import all your images and produce 1:1 previews. The next step is to pick the keepers and delete the rest. This makes it possible to erroneously delete perfectly good images because LR has not rendered them properly.

This issue manifests on a seemingly random basis every few months on my PC and I have been encountering this behavior at least since LR4 but maybe before.

Here are screenshots showing the issue. The file LR_Lib.png shows the problem, while LR_Dev.png shows how the file look after switching the the develop module.

Since I cannot rely on LR to render images properly, a somewhat sad statement, I use PhotoMechanic to make culling decisions.

Hi Rory, When this happens, does it just affect one photo or many photos in the develop module? Are you able to reproduce the issue at will? Does it happen with photos from all cameras for just from a particular camera?

What it is your Lr's standard preview size setting under Lightroom>Catalog Settings...>File Handling? Does it make a different if you choose Auto or some other preview sizes (for testing purposes, try restart Lr after you made the change).

If you zoom-in to 1:1 and then back, does the blurry previews get sharp?

Hi Simon - thanks very much for your attention to this!! See answers inline.

Hi Rory, When this happens, does it just affect one photo or many photos in the develop module? [Many photos in Library. Develop is not affected. Image rendering for an image in library works after returning from develop.]

Are you able to reproduce the issue at will? [NO, as described it is seemingly random and fairly rare].

Does it happen with photos from all cameras for just from a particular camera? [Good question - it must be multiple cameras since I have seen this behavior for a number of years. This instance was with a Nikon D810, shooting 14bit NEF with compression on]

What it is your Lr's standard preview size setting under Lightroom>Catalog Settings...>File Handling? [2048 pixels >> monitors are 2560 pixels. Also I have preview quality = medium and never discard 1:1 previews. The preview cache is 95 GB.]

Does it make a different if you choose Auto or some other preview sizes (for testing purposes, try restart Lr after you made the change). [Yes, they rendered correctly - I changed to auto. I should have just tried restarting without making the change to the preview size first, as I seem to recall this worked before.]

If you zoom-in to 1:1 and then back, does the blurry previews get sharp? [No]

[This is one of those issues that are hard to pin down because I cannot reproduce it]

Any followup? I'd hate to see this issue die on the vine again.

Sorry. I missed your earlier response. Thanks for the info. Given that this is a rare occasion and hard to reproduce, we need to continue to observe any pattern. I see you have a dual monitor setup.

When this happens, what sort of things that you do to get it unstuck? Relaunch Lr? Make a quick develop change? If you zoom to 1:1, does the 1:1 preview become resolved and sharp?

Try set the standard preview size to Auto going forward and see if things help.

I appreciate your attention to this Simon. To reiterate:

I have been seeing this problem on a rare and seemingly random basis for a number of years, at a guess at least since LR3 and maybe before that.

In library module zooming in and out does not help. When zoomed to 1:1 the image looks the same - it does not resolve and become sharp. When I switch to develop the image renders properly. When I return to library the image still looks blurry. I did not try making a change in quick develop.

I could only resolve the problem by exiting and reopening LR.

In the last problem instance, many, but not all of the images were not resolving completely. When I reopened LR they all resolved properly in Library.

Over the period I have been shooting with mostly Nikon cameras: D2h, D2x, D3, D3x, D700, D800E, D810.

At your prior suggestion I changed the preview size to auto. In the past the largest preview option has always been smaller than my monitor (2560*1600). However, I see that is not the case now, so perhaps this will solve the problem for me, but the issue will remain.

I have used one LR library since LR1. I would be happy to make it available to Adobe if you think that would help. It is fairly large at 1.3 GB.

It appears to me that there is some logic loophole where a flag is telling LR the image is already fully rendered.

Thanks Rory. My guess is that Lr might got stuck in some error condition (due to some kind of race condition) and the only way to clear it is to relaunch Lr. At this point, I would give the Auto standard preview size setting (which picks the size as the highest long edge of the attached monitors) a try. 

At this point, the catalog might not be helpful. Report back again if you run into the issue again and we go to the next step to collect more logs.
