This is definitely a bug. I can see it too, and it's little bit annoying. LR 4.1, Win7 x64.

To reproduce just select two images, render 1:1 previews to be shure they are present.

Then press 'N' to switch to Survey mode, and now press 'Z' to zoom in active photo.

It gets zoomed, but looks like LR zooms in standard (smaller) preview instead of using 1:1 preview - the result is blurry and a little pixelated, it definitely lacks resolution.

But when in the Loupe view (switch view using 'E') and zooming all work just fine - the image is at full resolution and is sharp.

And even if I switch from Survey to Loupe with zoomed in image - it still stays blurry.

To get sharp image I need to zoom out and then zoom in again.

So in short - it looks like 1:1 preview is used only when image is zoomed in from the Loupe view.

At least others seem to experience the same thing so I know it's not just me.  I'd say it's more than a little bit annoying because it causes you to second guess yourself and you constantly have to switch to a view to see if the image is actually sharp or not.  It really slows down the workflow.

I can't replicate the issue here James.  Which OS and which LR version?

I'm using Win7 64-bit and LR 4.1.  When I switch from Grid to Survey leaving nothing but the filmstrip at the bottom and highlight a bunch of images, then zoom (using 'Z') to look at any one of them, the image is fuzzy.  I go back to Grid View then Loupe View then zoom, the image is fine.  If I select an image while in Grid View, then use 'Z' the image may appear fine but if I toggle in and out of zoom, it will go blurry after the second zoom.  However, staying in Loupe View, I can toggle in and out of zoom numerous times and the image is always good.
