Lightroom 5: Loupe view not rendering properly all the time (x post)

I have noticed this as an occasional random ongoing problem in Lightroom and just encountered it again in LR 5, running on Win 7 64 on a 30" 2560x1600 monitor. While the develop view renders properly, the louple view is very soft. Here is an example:

1:1 from Develop



1:1 from loupe



There is no indication that you need to wait for the final rendering and the image never gets sharper. Zooming in and out does not fix the rendering in loupe view. Resizing the lightroom window to a smaller size does not help. Rebuilding 1:1 previews does not help.

The only thing that works is to close and reopen Lightroom. It appears that some flag in the program instructing the loupe rerender sometimes does not get set.

This is a serious problem because a user could easily decide to delete an image based on the loupe view. This has forced me to preview all my images in PhotoMechanic. I simply cannot rely on Lightroom.

This is a difficult problem to reproduce as it seems to happen randomly. Does anyone have a solution for this? In a search and based on recollection, the zoom in and out seemed to fix this in the past, but this does not work for me now.

If you apply a develop setting via quick-develop, will it update the loupe rendering? or does that not help either?

I'll give that a try next time it manifests Rob. I only see it periodically. It would be nice to have a work-around, but the primary issue is that I never know for sure that the previews have been rendered properly, which is not good when you are making deletion decisions.

I would be interested to know if anyone else has experienced this.

Got your point (and, I've never experienced it).

In my experience forcing zoom to 1:1 always clears rendering issues, which are occasionally stale or wonky.

PS - if develop settings change forces re-rendering, the work-around would be a preset which does something insignificant, but nothing significant (must be hand-created).

Did you try deleting *all* previews? (while Lr is not running) - then restart - if your preview data/database is wonked it could be the culprit.

That sounds like an excellent idea. I'll do that. Thanks for the help Rob!

I am going to delete all my previews with the view that it cannot hurt, but upon reflection, I am not sure this is the issue. If it was the problem then I would think that a restart of LR should not solve the rendering problem for an image if the preview database is corrupted.
