P: Pixelated or blurry preview in Library Loupe LR 4.3

Hi,

Sometimes in the Library module, the image displayed is pixelized, this often happens when I go back to a already reviewed image:



If I zoom to 100% then unzoom, the image appears sharp again.

This bug was not affecting LR versions <= 4.2 and is quite blocker for a photographic tool IMHO

Thx.
