I have an NSTextView where I've programmatically setDrawsBackground:FALSE on both itself and its NSClipView superview.

Instead of sending setDrawsBackground:NO (not FALSE) to the clip view, send it to the scroll view.

From the documentation:

"If your NSScrollView encloses an NSClipView sending a setDrawsBackground: message with a parameter of NO to the NSScrollView has the added effect of sending the NSClipView a setCopiesOnScroll: message with a parameter of NO. The side effect of sending the setDrawsBackground: message directly to the NSClipView instead would be the appearance of “trails” (vestiges of previous drawing) in the document view as it is scrolled."
