Aero flicker with VirtualBox 3D support

Any VirtualBox newer than 4.3.14 causes Aero UI elements to flicker or slow / not redraw when the mouse hovers over them when 3D support is enabled and the 3D driver is installed.

It has been noted that using a video driver other than the binary driver stops the flickering.

This has been seen on 340.xx series. Unsure if it is a VBox bug or NVIDIA bug.
