Aperture 3: Quick Preview temporarily looks jagged for recently imported images

Products Affected

Aperture 3.x

Symptoms

When you enable Quick Preview immediately after starting to import images, the new images may appear jagged in the Viewer.

Resolution

In Aperture 3 small thumbnails for each photo are imported almost instantly, allowing you to access, load, and work with newly imported RAW images immediately. The larger embedded JPEGs used by Quick Preview are imported immediately after these thumbnails appear. If you use Quick Preview on a photo before its embedded JPEG has been imported, the lower resolution thumbnail is temporarily used and may appear jagged.
