Overview
Set BackingStore to on to produce fast redraws of previously obscured windows. Disable BackingStore to use less system memory.
More Details
The term "backing store" refers to an offscreen pixel buffer used to store a copy of the figure window's contents. When you move or delete windows on your display, previously obscured windows can become exposed (even partially), requiring the computer system to redraw these windows. With backing store enabled, MATLAB simply copies an exposed figure window's contents from the buffer to the screen.
The BackingStore property is on by default because this provides the most desirable behavior. However, the offscreen pixel buffers required for each figure window do consume system memory. If memory is limited on your system, set BackingStore to off to release the memory used by these buffers.
