Created attachment 561803 [details] Reftest failure log I can reproduce these consistently when running tests locally on OS X 10.6. There are minor color differences like rgb(0,0,0)/rgb(1,1,1) or rgb(255,255,255)/rgb(254,254,254).
Many of the tests failing for me permanently have now been marked as fails-if(Android&&layersOpenGL). This might be an indication that having OpenGL layers turned on might be an important factor here. I will attach a patch that I'm maintaining locally to mark the tests which fail this way as 'fails'.
