Has anyone successfully used nested NSQuickdrawViews and
been able to make them opaque, to optimize drawing?
Whenever I return YES from isOpaque in my NSQuickdrawView
subclass, stuff no longer updates correctly. Calling
QDFlushPortBuffer() fixes this to some extent, but also
causes lots of flickering. QDAddRectToDirtyRegion() doesn't
help at all.
It seems that NSQuickdrawView is buggy. I'd appreciate
any insight that anyone has here.
