My screensaver vs. Aqua Icons

Thanks everyone for the advice on how to load images into a screensaver. Now I'm trying to make the images move, and am doing the obvious in animateOneFrame:

[myImageView setFrame:NSOffsetRect([myImageView frame],1,1)];

The image moves, and the quality is acceptable, but there's a twinge of flickering about it -- it's not nearly as smooth as the Aqua Icons screensaver.

Any ideas as to how I can remedy this? I'm assuming that, as with most things that I've been doing, lately, that this is a limitation in my knowledge rather than a problem with Cocoa.

In an air of experimentation I did override the backingStoreType; I got interesting displays with NSBackingStoreRetained and NSBackingStoreNonretained -- the screen alternated between myImageView on a black background and a completely white screen -- obviously not what I was hoping for.

TIA as usual,

Michael
