Lightroom: LR 4.2 displaying blurry grid images when in "import"

Did you not experience this problem with earlier versions?

What camera is that?

Nikon D300

Not a problem with 4.1, or 3.x

What camera are you shooting with?

You could try rebuilding the preview file.
Quit LR
Catalog settings > General > click Show > Doubleclick the Lightroom Folder > Delete the Catalog Previews.lrdata file
Restart LR

D300

Removed the Previews.Irdata directory, did not make a difference.

I would like to point out that there appears to be a blurry-causing bug on 4.2 that may be related to this, which is currently filed over here.

For me, the issue occurs on portrait-oriented photos, on the filmstrip AND secondary monitor, ONLY in develop mode. 100% reproducible. For the filmstrip, it only occurs when the item is active. If you then move to another portrait image, both thumbnails remain blurry. If you move to a landscape, the portrait thumbnails return to being sharp. Simultaneously, as the portrait image is rendered on the secondary display, it begins sharp and then turns blurry, with its thumbnail turning blurry at the same time.

The below image shows the phenomenon occurring on the filmstrip. Windows 7x64, ATI Radeon 5870 GPU, 16GB RAM, Intel Core i7 2600K, 256GB SSD, LR 4.2.

To reproduce, attach a second monitor and enable the Loupe (Normal) view on the Seconday Display. Then, enter Develop mode for a raw-format photograph. After adjusting the Shadows slider, observe that the loupe is blurry/pixelated until a manual zoom operation is performed on the loupe.

Those same steps yield the expected result in LR 4.1 (no blurry badness), but not in LR 4.2.

I'm on OS X 10.6.x, however this has been reported by users in many different OS configurations.

LR4.2 2nd Display Blurry.

In my case I am using a single display, and the problem is only in "import", "Develop" looks fine.

Paul,
Can you try with new catalog?
Create a new catalog, and import from there. Let us know if that is blurry as well.
This will rule out anything catalog specific, or point us to your catalog.

Also, can you provide us with any sample images that import blurry?
You can use dropbox, or similar service to share with us.

Thanks!
Pete

Pete,

Probably will not be able to get to it till next week. Having issues at work getting ready for Sandy, not a happy thought.

Just to clarify, they are not importing blurry, only blurry when in grid mode when selecting for import. If I go to single image display when in "import" they look fine.

This is happening with any photo regardless of camera, whether current photo, or years old, whether jpg, or nef.

If you are east coast, stay dry and safe!!
