For historical reasons the NSTextField fills its content with
NSRectFill, which uses the NSCompositeCopy compositing operation instead
of NSCompositeSourceOver. This will blow out your window content. Please
do file a Radar if you’d like to see this fixed.

Can you show us a picture of what your UI looks like? We may be able to
suggest an alternate solution.
