NSWindow -disableScreenUpdatesUntilFlush API (Section added since WWDC)
When a view that renders to a hardware surface (such as an OpenGL view) is placed in an NSScrollView or NSSplitView, there can be a noticeable flicker or lag when the scroll position or splitter position is moved. This happens because each move of the hardware surface takes effect immediately, before the remaining window content has had the chance to draw and flush.
