I have just installed F16 on my LG X200 Netbook that comes with Intel Embedded Graphic Card. At the beginning everything seemed fine until I started to notice a weird behaviour with GNOME3 Application Menu; whenever I scroll up or down the screen starts flickering with big purple distort displayed on the screen. I could not see any error message that could help me to start debugging the issue. I took a screenshot of my monitor and I uploaded to this thread. I hope someone in this forum could help me or give me a clue of what went wrong. Thanks
