Rotated NSImage drawAtPoint:... slow

Subject: Rotated NSImage drawAtPoint:... slow

I just finished working on a view that draws some stuff at an angle including an NSImage created from a tiff with alpha. It worked great in the test project with no noticeable performance issues. I imported it into my main project and hooked it into my view hierarchy and it now hangs for about 8 seconds while loading the view. Looking at samples all the time is being spent in -[NSBitmapImageRep loadData] for that image (its only 138x188px). If I comment out the drawAtPoint: call that draws the image the view loads without any hang time. Any thoughts on why this would be happening? This is on 10.4.11.
