I'm not sure what that patch is supposed to do.

ddraw_width and ddraw_height are the width and height of the current
screen. For fullscreen applications that's the same as the backbuffer,
but for windowed applications the backbuffer is smaller. I think it
would make more sense for the initial scissor rect to be the size of
the backbuffer than the size of the screen. Also keep in mind that a
device might have multiple swapchains, not all of which might have the
same backbuffer dimensions.
