I'm having an odd problem with CoreAnimation. I have a CAScrollLayer
that contains a bunch of sublayers. I change the position of the
scroll layer, and suddenly all the sublayers become blurry.
Before scrolling they look like this:

After scrolling they look like this:

Has anyone else run into this? It seems to be a redraw issue. I do
an initial positioning before the scroll layer draws and that
doesn't seem to blur the sublayers.
It looks like at least some of the layers are displaying bitmap
images. Is it possible that the when you scroll the images are ending
up not aligned to screen pixels and as a result they are being
antialiased as they are rendered?
