Secondary Window Loupe is blurry or pixelated after making Develop adjustments in Lightroom 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.

Same issue on Win7x64

I'm seeing this problem with portrait images on the Develop module ONLY, even with NO adjustments applied. The image renders on the secondary display and for a brief moment is perfect and then a blur sets in. It's set to Fit. If I zoom, it zooms sharp. If I zoom back out, it stays blurry. If I switch to the library module, the Loupe view goes BACK to being sharp at the primary "Fit" zoom level.

This occurs in 4.2 for me, on a Windows 7x64 machine with a Radeon 5870, Core i7 2600k with 16GB of ram, and all previews rendered 1:1.

This appears to primarily/only occur on portrait-shot photos, and again, only in the develop module. (I have noticed some weird "adjustment" that was appearing on my very first pass through these photos through the Develop module, even though no default adjustments or changes were set. The photo would typically lighten up, almost as if a monitor or colorspace profile was changing, or something.

I have two Dell U2412m eIPS displays, and changing which display is the primary doesn't solve the problem. The Develop module still blurs portrait photos on the secondary Loupe display.

I'd like to add to this issue that the phenomenon is also occurring in the filmstrip. Again, for me, this ONLY occurs with portrait photos, and ONLY in the Develop module. Switching back to Library makes all thumbnails and secondary display sharp again.

This bug may be related as well.

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. Again, switching to Library mode instantly removes the blurry effect, both from the thumbnail in the filmstrip on my primary display, and from the secondary Loupe view. Disabling the secondary display does NOT solve the problem on the filmstrip.

The below image shows the phenomenon occurring on the filmstrip.



(You'll want to click the image to view it at full-size to examine the blurriness of the two portrait images. I've noticed that the previously selected portrait image will sometimes go back to being sharp, but it's somewhat random, it appears.)

On the primary monitor, where you are in Develop, do you have the Navigator panel showing? If the Navigator is collapsed or hidden, try showing it and expanding the panel. I was able to reproduce the fuzzy behavior mentioned here, but only when the Navigator wasn't showing. I'm curious if this is the same issue you are seeing or not.

Thanks,
Becky

Navigator pane is open. Makes no difference if open or closed, blurry all the time, always in develop mode, 2nd monitor and in filmstrip. But again, only on portrait shots.
