No, it will also happen, if I use only one NSView and draw a
NSRectFill() with white color before drawing the CIImage. The problem
has nothing to do with the fact that in this example project are two
NSViews.

It looks to me like you have two overlapping views. Cocoa does not
support this, although it may happen to work right sometimes.

Hi,
I created a CoreImage composition using some CIFIlters. The result
of the composition is a semi-transparent image. This is all
working without any problems when I draw the image into an empty
NSView. Now I concat a NSAffineTransform and rotate the graphic
context. Also working well..
But If I start drawing anything in white color behind this NSView
(even another NSView, e.g. NSColorWell), the result will be bad on
PowerPC Macintosh (tested G4 and G5) but good on Intel Macs (iMac
+ Mac Mini tested).
I created a test project on http://www.thomasdingler.de/dev/
CoreImageTest.zip (61Kb)
The result on Intel Mac is like: http://www.thomasdingler.de/dev/
CoreImageTestIntelMac.png (20kb)
The result on PPC Mac is like: http://www.thomasdingler.de/dev/
CoreImageTestPPCMac.png (22kb)
Any Ideas???
Best regards,
