The course of their work in graphics, Z buffer, framebuffer and texture buffer memory bandwidth will be substantially occupied resources.
在显卡工作过程中，Z缓冲器、帧缓冲器和纹理缓冲器都会大幅占用显存带宽资源。

The window server provides a region of Shared memory to clients for drawing and then composites this into the framebuffer (on the GPU).
窗口服务器为客户提供了一块共用内存区域用来绘图，然后(用gpu)将其混合为帧缓冲。

The obvious disadvantage to this was that all processes had access to the framebuffer, so could corrupt the display easily and synchronizing drawing between applications was very difficult.
