A thinkpad x220i machine.
I donnot know how to reproduce this problem with 100% probability. But
it seems to occur when both firefox 8.0 and google chrome 18.0.1025.39
beta are running and some of them trying to open some dynamic
content(dynamic picture, video). There will be stripes crossing the
screen. For more information, feel free to drop message.
