Okay, so, here's the solution … The problem was in this … Wrong way
I was listening for contentView frame changes (NSViewDidChangeFrameNotification) and I was calling display/invalidateShadow whenever I receieved this notification. Correct way NSWindowDelegate has windowDidResize notification. I moved display/invalidateShadow there and it stops flickering and works perfectly now. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
