I tried it on QPC2. I can see that the red and green components of the colour block are one pixel to the right of the blue component. If the inner block is drawn white, you get a thin strip (one pixel?) of blue on the left and the same of yellow (=red+green) on the right hand side. Choosing other colours for the inner block shows how the different colour pixels are drawn offset.
I haven't got a BBQL set up to try it, but the effect doesn't happen on QemuLator v3.3.1 with a JS ROM image.
