Because the DWM is in charge of compositing the screen, it can render translucent and blurred areas of the window. Previously, dragging a window could create visual artifacts, as described. ![]() When a window is obstructed by another window, the obstructed window does not need to repaint itself. The DWM provides several advantages over the old graphics architecture. The DWM then composites these surfaces to the screen. Instead, each window draws to an offscreen memory buffer, also called an offscreen surface. When the DWM is enabled, a window no longer draws directly to the display buffer. Windows Vista fundamentally changed how windows are drawn, by introducing the Desktop Window Manager (DWM). If the repainting is too slow, it causes the artifacts shown in the previous image. As the top-most window is dragged, the window below it must be repainted. The trail is caused because both windows paint to the same area of memory. For example, if the user drags one window over another window, and the window underneath does not repaint itself quickly enough, the top-most window can leave a trail: This approach can cause visual artifacts if a window does not repaint itself correctly. In other words, the program would write directly to the memory buffer shown by the video card.
