System works fine util Suspend.
After wake up from Suspend video on display stutters.
Video (e.g. in browser) freezes approximately once every second, and freeze
lasts for about 100 millisecond.
If you drag an icon or a window over the desktop, the icon will stutter, but
the cursor will not stutter.
