I have zero expertise in this area, but in case it is related: Juan Vuletich posted a fix yesterday in Mantis 7376: "Bug in BitBlt (rgbMul sets alpha to 0)". I can't tell if this relates to the problem you are describing, but FWIW Juan's fix is in the latest VMMaker on SqueakSource (as of yesterday), so if you are building your on VM you can try it and see if it makes a difference.
