It still fails on Qt on r135862 - http://build.webkit.sed.hu/results/x86-64%20Linux%20Qt%20Release/r135862%20%2845465%29/fast/backgrounds/background-opaque-images-over-color-diffs.html

and it still fails on Apple Mac on r135863 - http://build.webkit.org/results/Apple%20Lion%20Release%20WK1%20%28Tests%29/r135863%20%286600%29/fast/backgrounds/background-opaque-images-over-color-diffs.html

Looks like the new test uncovered a compositing bug in the Qt port.  The diff on the mac port looks like it is just numerical rounding issue in the blending arithmetic.  I think the correct course is to add TestExpectations and file new bugs.
