I'm trying to do some animation where each time drawRect is called it's drawing over what was previously drawn, but something is erasing the view. I've setBackgroundColor for the window to clearColor so it's no longer drawing the default stripes but now it's erasing to black.

I think NSWindow has an isOpaque method. You might have to override that.

Also, you're not using NSRectFill() to erase to clearColor, right? Because that's equivalent to NSRectFillWithOperation() using the 'copy' mode.
