When we added this property to the Canvas and ContainerControl there was probably a lot of head scratching going on. Some of you probably asked yourself (or us) “Why is this necessary?” or “Isn’t this pretty much the same thing as enabling DoubleBuffer?”

Well, yes to the latter question on Windows, and a slightly more optimized experience on OS X, but the impetus behind this property was really our redesigned IDE. More specifically, it was a need/requirement because of a long standing issue with our Linux framework.

Linux, especially Ubuntu, has quickly evolved, introducing core UI changes such as the global menu bar (akin to OS X’s single menubar system) as well as Overlay Scrollbars. Overlay Scrollbars were meant to reduce the amount of clutter needed around content areas by showing up only when hovered over, and always outside the content area. If you’re developing any kind of serious application on Linux, especially if you are targeting Ubuntu, you want to be able to detect whether or not the system supports Overlay Scrollbars.
