Make sure your screen display format for d3d9 is ARGB not XRGB. I have my desktop set to 32bits yet I only get 24bits of channels. So don''t pass the queried format straight into d3d9, intercept it and change it to argb 32bit format. It took me some time to figure out my dest. alpha wasn''t being written to and I thought my multitexture multipass setup was buggy.
