Wouldn't that just do the same as color 1.0, 1.0, 1.0? If I understand d3drm_color_component right the color floats range from 0.0 to 1.0. No such thing as true floating point render targets in ddraw :-)

Yeah, anything >1.0 gets clamped to 1.0 (full intensity).
So this is white, and the surface is already white... a different color needs to be selected for verifying that Render does not clear the surface.
