用glxgears -printfps查看，帧数只有900多，但如果把glxgear的窗口最小化，帧数就上到50000左右，为什么会这样呢？是不是驱动没有装好？
ubuntu@ubuntu-desktop:~$ fglrxinfo display: :0.0 screen: 0
OpenGL vendor string: ATI Technologies Inc.
OpenGL renderer string: RADEON 9800 Pro Generic
OpenGL version string: 2.0.6011 (8.28.8)
ubuntu@ubuntu-desktop:~$ glxgears -printfps
962 frames in 5.0 seconds = 192.347 FPS
934 frames in 5.0 seconds = 186.788 FPS
972 frames in 5.0 seconds = 194.225 FPS
50558 frames in 5.0 seconds = 10111.435 FPS
50714 frames in 5.0 seconds = 10142.628 FPS
50496 frames in 5.0 seconds = 10099.117 FPS
安装ATI 8.28.8驱动后的怪现象。
