This showed up as https://bugzilla.mozilla.org/show_bug.cgi?id=433917  
-- it seems to happen on linux and win32, though I haven't tried  
reproducing it on win32.  The attached testcase shows the problem;  
I've also attached the ref rendering from the image backend.  If the  
first paint_with_alpha has an alpha value less than 1.0, then..  
strange things happen, I'm not even sure exactly what.  I'll try to  
figure out a regression range in the next few days, though if someone  
wants to beat me to it, please feel free :)
