This should be fixed in SVN now.
Even after using paint instead of fill for some composition modes the resulting TIFF file looks different to the displayed image. But this is also the case on MacOSX, so I don't see it as an error.

See the TestApp. Using art backend, the compositing operations work as expected (except Highlight). Cairo backend gives bad rendering of view when using NSFillRectUsingOperation(rect, op) when op = {SourceIn | SourceOut | DestinationIn | DestinationATop | PlusDarker}. The strange part is that if one exports the view as a bitmap image, the composited image is OK. Only the rendering in the view is wrong.

System: Suse Linux 10.1; Parallels Virtual Machine over Mac OSX; GNUstep svn 24903
