Bug Description
[Impact]
The Intel video driver has a bug that can cause to incorrectly draw certain trapezoids. This is visible when using client side decorations in GNOME 3 (see attached screenshots).
[Test Case]
Run GNOME 3 with client side decorations on Intel hardware.
Observed result:
Shadow under window is missing corners.
Expected result:
Shadow looks correct.
[Regression potential]
Low. The fix is from upstream and just changes the logic error in the CompositeTrapezoids routine.
