I am blitting DD7 surfaces onto my backbuffer. My problem is that my transparent color is not transparent. Instead, it displays vertical lines, one transparent, one with the color that was supposed to be transparent, and so one. What''s happening ? Anyone would help please ?

Make sure the size of the destination and source rects are equal. I''ve run into similar problems when they were off by one or something like that.

Dest and source rects do not have to be equal. Eit her one can be larger or smaller than the other. Are you converting your transparent color to the current bit depth before you send the value to the surface?
