When getting a CGImage via [myNSBitmapImageRep CGImage] to feed a CALayer, Core Animation may crash as detailed here : Changing CALayer's contents too rapidly causes CoreAnimation to implode. The given solution is to keep myNSBitmapImageRep around, retaining it.

Another workaround is to render the bitmap now : after creating your layer and setting its contents , use [CATransaction commit] and CA will draw it right away. CA will then display everything correctly, and you can forget about myNSBitmapImageRep.
