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.
