Running Compiz on SNB, some part of the screen has render flaws.
To be fixed in 7.9.1
This needs details. With wobbly windows, window movement, and whatever produces desktop transitions (but not desktop cube), the only issue I've found is that when dragging a window to provoke desktop transition the transition is black instead of something expected (like the flip of the screen that happens if I control-alt-left/right)
I confirm with Eric's observation.

i965: Add user clip planes support to gen6.
Fixes piglit user-clip, and compiz desktop switching when dragging a
window and using just 2 desktops. Bug #30446.
The issue described by Eric has been fixed with the latest code.
So verified the bug.
