Downloaded the new Windlight. Things looked pretty nice, so I zoomed back to get a full-sim pic.
Picture comes out fine as an in-world snapshot. But when I tried saving one to disk? Bleah! Horizontal stripes of un-rendered content made my sim look like it had been put through an egg slicer! Initially tried 1024 x 1024 resolution to disk, and then tried 512 x 512. Same problem both times. Looks just as crummy in the preview in the snapshot controls, too.
