Hi Riccardo,
I get this too with GSUseGhostResize YES. It's not clear to me how the ghost 
resize code in NSSplitView is supposed to work. Is that code expecting 
NSHighlightRect to be a bitwise XOR where drawing the same rect twice gives you 
the original image back? NSHighlightRect doesn't appear to do that, at least 
with cairo.

e.g. see http://lists.cairographics.org/archives/cairo/2004-July/001593.html
